So if line FD is the 3rd and 1st letters of the first triangle, then it has to be equal to the 3rd and 1st letter of the 2nd triangle.
IK
Another way to do this is that when you find FD on the triangle you can set that the line has 3 tally marks. Then look at the other triangle and find a line in which there are 3 tally marks.
The order in which you put the letters does not matter. IK and KI should both be considered correct

The first number is 5 less than 3 times the second number. Four times the first number
minus two times the second number is ten. Find the numbers.
Answers
Answer:
The first number is 4, the second is 3
Step-by-step explanation:
We can make 2 equations, let x be the first number, and y be the second number.
x = 3y - 5
4x - 2y = 10
We sub x = 3y - 5
=> 4(3y - 5) - 2y = 10
=> 12y - 20 - 2y = 10
=> 10y - 20 = 10
=> 10y = 30
=> y = 3
Sub y = 3 into x = 3y - 5
x = 3(3) - 5
x = 4
Therefore, the first number is 4, and the second is 3

What are triangle?
A triangle in geometry is a three-sided polygon with three edges and three vertices.
The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic.
This characteristic is known as the triangle's angle sum property.
If ABC is a triangle, it is written as ABC, where A, B, and C represent the triangle's vertices.
In Euclidean geometry, a triangle is a two-dimensional shape that is represented by three non-collinear points in a single plane.
A closed, two-dimensional shape is a triangle. It is a polygon with three sides. Straight lines make up all of the sides.
The vertex is the intersection of two straight lines. The triangle therefore has three vertices.
According to our question-
We are given a side and an adjacent angle, and we must figure out which side or angle is needed in order for SAS to provide proof.

Answers
On solving the provided question we can say that the radius of circle is 2.1415 cm.
What is circle?Every point in the plane that is a certain distance away from a certain point forms a circle (center). It is, thus, a curve formed by points moving in the plane at a fixed distance from a point. At every angle, it is also rotationally symmetric about the center. A circle is a closed two-dimensional object where every pair of points in the plane are equally spaced out from the "center." A line that goes through the circle creates a specular symmetry line. At every angle, it is also rotationally symmetric about the center.
We know, Central angle (θ) = (length arc)/radius ….(1)
Convert angle in radian:
Angle in radians = Angle in degrees x π/180° = 197° x π/180 = 1.09
From (1),
Radius = (length arc)/Central angle
= 8/3.1415 =2.1415cm

How do you find the ratio of a circle formula?
Answers
The ratio of a circle can be found through the formula A = πr2, where A is the area of the circle and r is the radius of the circle.
To find the ratio of a circle, you must first calculate the area of the circle. To calculate the area, multiply the value of π (3.14159) by the square of the radius (r2). For example, if the radius of the circle is 4, the area of the circle would be 3.14159 x 42, which is equal to 50.2653. The ratio of a given circle can then be found by dividing the area of the circle (50.2653) by the square of the radius (42), which gives 1.273.

What is wages?A wage is the payment made to employees for the time they put in working for their employer. Always based on a specific period of time, wages are paid. On an hourly basis, typically. This is the origin of the phrase hourly worker. Salary and commissions are some additional types of payment.
Pay for lower level employees is determined by the number of hours worked. To record the number of hours worked each week, these employees typically use a time sheet or time card. To keep track of hourly employee hours, the majority of modern employers use computerised systems.
To enter their hours worked, employees must log in and out of the system. These workers are then paid either weekly or biweekly, depending on the state.
Given that the owner pays herself twice the sum of the other employees' weekly wages.
Sum wage of the employees = $157.50 + $189.00 + $220.50+ $252.00+ $283.50

y=x^2+6x+8 solve by completing the square.
Answers
For the given quadratic equation, the solutions are x = -3 and x = -3.
What is the completing square method?
The completing the square method is a technique used to solve quadratic equations of the form y = ax² + bx + c. The goal of this method is to convert the equation into the standard form of a quadratic equation, which is y = a(x + h)² + k, where a, h and k are constants.
To solve y = x² + 6x + 8 by completing the square, we need to add and subtract a value to the equation so that the x-term (x² + 6x) is a perfect square. In this case, we need to add and subtract (6/2)² = 9 to the equation, which gives us:
y = x² + 6x + 8
y = (x² + 6x + 9) - 1
Now, we can take the square root of the x-term, which is (x + 3)², and we get:
y = (x + 3)² - 1
The equation is now in the standard form of a quadratic equation, with y = (x + 3)² - 1. We can now solve for x by taking the square root of both sides of the equation and getting x = -3, -3 .
Alternatively, We can also solve for x by factoring the expression inside the square, which would give (x + 3) (x + 3) = 0 and x = -3, -3
Hence, for the given quadratic equation, the solutions are x = -3 and x = -3.

What is volume of cylinder and cone?Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface. The unit of volume is in cubic units such as m3, cm3, in3 etc. Sometimes, volume is also termed capacity.
The volume of a cone is linked to the volume of a cylinder. A cone is one third of the volume of a cylinder. The volume of a cone is ¹/₃ × π × r² × l. To calculate the volume we multiply these values together.
The volume of cylinder = πr²h
and volume of cone = 1/3 πr²h
since the volume of the cone and cylinder are equal
πr²h = 1/3 πr²h
r in cylinder = x cm and h is 2x
r in cone = x cm
therefore πx²×2x = 1/3πxh
divide both side by πx
π2x³/πx = h/3
2x² = h/3

Jon and Becky measured the circle-shaped part of a sun they drew on the sidewalk. The diameter of the circle is 66 centimeters. What is the approximate area of the circle? (Use 3.14 for .) A. 854.865 cm2 B. 3,419.46 cm2 C. 207.24 cm2 D. 13,677.84 cm2
Answers
The correct option for the area of the circle is B. 3,419.46 cm².
What is area of a circleThe area of a circle is π multiplied by the square of the radius. The area of a circle(A) when the radius 'r' is given is πr².
Area of circle = πr²
π = 3.14
radius = diameter/2
radius of the circle = 66 cm/2
radius of the circle = 33 cm
Area of the circle = 3.14 × (33 cm)²
Area of the circle = 3.14 × 1089 cm²
Area of the circle = 3419.46 cm²
Therefore, the area of the circle measured by Jon and Becky is equal to 3,419.46 cm².

What is the value of R in the equation 2 2r 8 3r 16 4 points a 0 b2 C 10 D 32?
Answers
The equation 2 2r 8 3r 16 is a linear equation in two variables (r and 3r).
To solve for r, we can use the method of elimination. First, we subtract the second equation from the first equation:
2 2r 8 3r 16
-2 2r 8 3r 16
------------------------
0 0 0
Since the equation is now equal to 0, this means that r is equal to 0. We can confirm this by substituting 0 in for r in both equations:
2 2(0) 8 3(0) 16
2(0) 8(0) 16
0 0 16
Since 0 = 16 is not true, this confirms that r = 0.
