Answer:
mTW = 230
Step-by-step explanation:
Remark
You have to assume that O is the center of the circle. Two sectors are marked as equal, so equate them to find x
Equation and Solution
5x + 5 = 4x - 20 Subtract 5 from both sides
5x + 5 - 5 = 4x+ 20 - 5 Combine
5x = 4x + 15 Subtract 4x from both sides.
5x-4x = 4x-4x + 15
x = 15
TOU = 5*15 + 5 = 80
VOW = 80 TOU and VOW are marked as equal
UOV = 6x -20 = 70
Total of all three = 80 + 80 + 70 = 230
