Answer:
b, x = 17
Step-by-step explanation:
A right angle (as shown by the box in the corner of the angle) is 90°.
So, the two angles have to add up to 90°.
22 + 4x = 90
Subtract 22 from both sides.
4x = 68
Divide both sides by 4.
x = 17
The answer is b, 17

Answer:
12 multiple choice questions
Step-by-step explanation:
The system of equations is:
m + t = 19 (quantity of questions)
6m + 4t = 100 (point value)
We use elimination to solve.
Multiply everything in the first equation by 4.
4m + 4t = 76.
subtract that from the second equation.
2m = 24
Divide both sides by 2.
m = 12
Answer:
The value of x is 32.
Step-by-step explanation:
Because all of the sides are equal, we know all of the angles are equal. Since there is only 180 degrees in a triangle, we know each angle is equal to 60 degrees. Therefore, we can set angle Z equal to 60 degrees.
2x - 4 = 60
2x = 64
x = 32
The answer is 1487.9286. hope you have a good day or night.
