How is solving for the length different from solving for the length of the hypotenuse?
Answers
The ratio between the sides of this triangle is 1:1:Sqrt(2), which means that the length of the legs are equal, and the length of the hypotenuse is simply the leg length multiplied by the square root of two.
Could someone help with this pls?
Answers
Answer:
61
Step-by-step explanation:
Because all triangles's angles sum is always equal to 180, we can establish the equation, (9x - 31) + (7x - 2) + (4x + 33) = 180.
Simplifying, we get;
9x - 31 + 7x - 2 + 4x + 33 = 180
20x = 180
x = 9.
So, angle DCE = 7x - 2 = 7 * 9 - 2 = 63 - 2 = 61

Answer:
The exact value of tan A in simplest form is [tex]tan (A) = \dfrac{9}{40}[/tex]
Step-by-step explanation:
The parameters of the given right triangle are;
The length of the hypotenuse side = 41
The length of the vertical leg of the right triangle = 9
The length of the opposite leg of the right triangle = 40
By trigonometric rule, we have;
[tex]tan (A) = \dfrac{Opposite \ leg \ length \ to \ angle \ A}{Adjacent \ leg \ length \ to \ angle \ A }[/tex]
Therefore, we have;
[tex]tan (A) = \dfrac{9}{40} = 0.225[/tex]

NEED HELP NOW Angles not necessarily drawn to scale
Answers
x = 56
Explanation:
You have a straight angle, and you’re given 2 angles. And since there are 3 angles that make up 180, we do:
180 - 64 - 60 = 56.
Hope it helps. ^^
Answer:
x= 56
Step-by-step explanation:
since angle DF is half a circle it has to = 180 so you subtract 64 from 180 then you subtract 60 from that
The polynomial x^2-18x+81 represents the area(in square feet) of a square courtyard. Write an expression for the perimeter of the courtyard.
Answers
Answer:
4x - 36 feet
Step-by-step explanation:
The area A of a square whose sides are s units is given as
A = s * s
Given that the area A = x^2-18x+81, factorizing
A = x^2-9x-9x+81
A= x(x-9)-9(x-9)
A = (x-9)(x-9)
A = (x-9)^2
This means that the size of each side of the square courtyard is x-9 feet long
Recall that the perimeter P of a square whose side is s long is given as
P = 4s hence since the side of the courtyard is x - 9 feet, the perimeter of the courtyard
P = 4(x-9)
= 4x - 36 feet

Addison has read 102 pages so far and decides to read 16 pages every day until she finishes the book. Bert has read 142 pages, and he plans to read 11 pages every day. How many days will it be until Addison and Bert have each read the same number of pages in total? How many pages will they each have read?
Answers
Answer: The answer in this photo thanks for a little quiz
The number of day it will be until Addison and Bert each have read the same number of pages in total is 8 days.
What is an equation?In mathematics, an equation is a statement of equality between two expressions, indicated by the equals sign (=). Solutions to equations are the values for unknowns which, when substituted into the expression, make it true.
Given that, the book they're reading right now is 256 pages long.
Let the number of days be x.
Addison has read 102 pages so far and decides to read 16 pages every day until she finishes the book.
102+16x -------(i)
Bert has read 142 pages, and he plans to read 11 pages every day.
142+11x -------(ii)
Addison and Bert have each read the same number of pages in total.
So, (i)=(ii)
102+16x=142+11x
16x-11x=142-102
5x=40
x=8
Hence, the number of day it will be until Addison and Bert each have read the same number of pages in total is 8 days.

Find the sum 1.56 + 0.083. Show your reasoning
Answers
Answer:
1.643
Step-by-step explanation:
1.56 + 0.083
1.56 = 1.560
Starting from the digits the closest to the right, we do
0.003 + 0.000 = 0.003
0.08 + 0.06 = 0.14
so right now we have 0.143
0.0 + 0.5 = 0.5
so now we have 0.643 (because 0.1 + 0.5 = 0.6)
and finally 1 + 0 = 1
so we end with 1.643
The sum of the expression 1.56 + 0.083 is,
⇒ 1.643
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
The expression is,
⇒ 1.56 + 0.083
Now, We can simplify as;
⇒ 1.56 + 0.083
Add as;
⇒ 1.643
Thus, The sum of the expression 1.56 + 0.083 is,
⇒ 1.643
