Answer:
x = 18.75
Step-by-step explanation:
The angles are alternate interior angles and alternate interior angles are equal when the lines are parallel
3x-10 = 65-x
Add x to each side
3x-10+x = 65-x+x
4x-10 = 65
Add 10 to each side
4x-10+10 = 65+10
4x = 75
Divide each side by 4
4x/4 = 75/4
x = 18.75

u take ur known variables and fill them in, pi will be filled in as 3.14
Example:

Then divide both sides by 3.14, after that it should be (number) =r². since it's squared you have to find to square root of both.
Example:

therefore in this example the radius is 7
Step-by-step explanation:
1. set it equal to 0 so t=5,9
2. this is wriiten in vertex notation so vertex is (7,4)
