In the triangle below, what is the length of the side opposite the 30 degree angle?
Answer:
A. 3/2
Step-by-step explanation:
To find the lenght of the side opposing the 30° angle, you need to use trigonometry, since it's a right-angled triangle. You have your 30° angle and you have the side beside : therefore, you can use the sine :
sin(30) x 3 = ?
0,5 x 3 = ?
1,5 = ?
1,5 = 3/2
6. Find the measure of each
marked angle.
The measure of each marked angle is 60 degrees for the given figure, which are alternate exterior angles.
The angles are given as:
∠1 = 10x-20 and ∠2 = 7x+4
As we know that alternate exterior angles are described as the pair of angles formed on the outer side of the parallel lines and on opposite sides of the transversal when two parallel lines are crossed by a transversal.
By alternate exterior angles, it can be written as:
∠1 = ∠2
10x-20 = 7x+4
10x -7x = 4 + 20
3x = 24
x = 24/3
x = 3
From given angles:
80 - 20 = 60
56 + 4 = 60
Thus, the measure of each marked angle is 60 degrees.

Angle 1 (x + 4)
Angle 2 (3x + 2)
Angle 2 (2x)
Angle 2 (4x)
Answer/Step-by-step explanation:
Problem 1:
✔️Type of angle = right angle
✔️Equation: (x + 4) + (3x + 2) = 90°
✔️value of x:
x + 4 + 3x + 2 = 90
Add like terms
4x + 6 = 90
4x = 90 - 6
4x = 84
x = 84/4
x = 21
✔️Angle 1 (x + 4):
Plug in the value of x
Angle 1 = 21 + 4 = 25°
✔️Angle 2 (3x + 2):
Angle 2 = 3(21) + 2 = 63 + 2 = 65°
Problem 2:
✔️Type of angle = right angle
✔️Equation: x + 2x = 90°
✔️value of x:
x + 2x = 90
Add like terms
3x = 90
x = 90/3
x = 30
✔️Angle 1 (x):
Angle 1 = x = 30°
✔️Angle 2 (2x):
Angle 2 = 2(30) = 60°
Problem 3:
✔️Type of angle = right angle
✔️Equation: (3x + 6) + 4x = 90°
✔️value of x:
3x + 6 + 4x = 90
Add like terms
7x + 6 = 90
7x = 90 - 6
7x = 84
x = 84/7
x = 12
✔️Angle 1 (3x + 6):
Plug in the value of x
Angle 1 = 3(12) + 6 = 42°
✔️Angle 2 (4x):
Angle 2 = 4(12) = 48°

Answer:
x = 3.2
Step-by-step explanation:
Since, intercepts made by parallel lines on the transversals are in proportion.
[tex] \therefore \frac{AB}{BC} =\frac{EF}{FG}... (1)[/tex]
AB = BC.... (given)
[tex] \implies \frac{AB}{BC} = 1..... (2)[/tex]
From equations (1) & (2)
[tex] 1 =\frac{EF}{FG}[/tex]
[tex] {FG}={EF}[/tex]
Therefore,
7x - 9 = 2x + 7
7x - 2x = 9 + 7
5x = 16
x = 16/5
x = 3.2

Triangle abc is equilateral, solve for x and y
Answer:
x = 4
y = 3
Step-by-step explanation:
Remark
If a triangle is equilateral all three sides are equal. So each side has equal statements.
Solution
3x + 2 = 5x - 2y Subtract 3x from both sides
2 = 5x -3x - 2y Combine
2 = 2x - 2y divide by 2
x - y = 1 Equation 1
3x + 2 = 6y - 4 Equilateral triangles have equal sides. Subtract 6y
3x - 6y + 2= - 4 Subtract 2
3x - 6y = -4 - 2
3x - 6y = - 6 Divide by 3
x - 2y = - 2 Equation 2.
Now subtract equation 1 from equation 2
x - 2y = - 2
x - y = 1 Subtract
- y = - 3 Multiply by -2
y = 3
Put y = 3 into equation 1
x - y = 1
x - 3 = 1 Add 3 to both sides.
x = 4
Answer
x = 4
y = 3

Let us write down the coordinates of the snow tubing and the ski lift.
Ski Lift = (3 , -4)
Snow Tubing = (3, 3)
We want to find the distance, which can be found by subtracting their y coordinates from each other.
-4 - 3 = 7

Solve the equation for y. Show work.
6x−4y=24
Answer:
y = -3/2x + 6
Step-by-step explanation:
We won't be able to figure out Y in number form, since we have a second variable, but we can figure it out in terms of X.
First, we have to subtract 6x from both sides
( -4y = -6x + 24 )
Then we have to divide both sides by -4
( y = -3/2x + 6 )
This is our final answer in terms of x

Answer:
5,720,000 Sq Feet.
Step-by-step explanation:
They are asking the Area of a Trapezoid
Equation =( base + base / 2) x height
Lets first set it up. We know that A-B is 200 feet. & D-C is 260. They are both the bases.
So if you multiply them (200 x 260) You will get 52000.
Now we divide that by 2. (52000 / 2 = 26000)
Now it says the straight line is 220. I think this refers to the height.
Now we multiply 26000 x 220. Which is 5720000.
Its a pretty big number, but that is the answer! :)

Jake spent a three-day weekend on the lake. On Saturday, he rented a pontoon boat for three hours and paid $435. On Sunday, he rented the same boat for five hours and it cost him $190 more than it di the day before. If he rented the same boat on Monday for just two hours, find the total cost to rent the boat for three days.
Answer:
1400
Step-by-step explanation:
There is a flat fee involved, which is the y-intercept of the line.
The line eats the points:
(3, 435)
and
(5, 625)
the slope is 190/2 = 95
B = y - mx = 435 - (95)(3)
= 435 - 285
= 150
The linear function is:
y = 95x + 150
So for x=2, it will cost
95(2) + 150 = 190 + 150 = 340
435 + 625 + 340 = 1400
The total cost to rent the boat for three days is $1400.
Given that, on Saturday, he rented a pontoon boat for three hours and paid $435.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The cost for the rented a pontoon boat for five hours is 435+190 = 625
The coordinate points are (3, 435) and(5, 625)
The slope is m = (625-435)/(5-3)
= 190/2 = 95
Now, b = y - mx = 435 - (95)(3)
= 435 - 285 = 150
So, the linear function is y = 95x + 150
So for x=2, it will cost
95(2) + 150 = 190 + 150 = 340
Total cost = 435 + 625 + 340 = 1400
Therefore, the total cost to rent the boat for three days is $1400.
