C = 2πr Divide both sides by 2π
C/2π = r Switch the sides to make it easier to read
r = c / 2π

no problem?
Step-by-step explanation:
Answer: x=7
Step-by-step explanation:
Since AB is a bisector, it cuts the angle in half, and since we know that the angle is a right angle, we know it’s 90 degrees, so knowing that you use the equation 7x-4= 45 (since 45 is half of 90), add 4 to both sides so you have 7x=49, the divide 49 by 7 and you get 7, so x= 7
