Question

For the image above, find the following:

x =

ACB =

Answer 1

Answer:

x = 25

m∠ACB = 115°

Explanation:

ACB = 4x + 15 = 4(25) + 15 = 115°

Answer 2

x = 25

m∠ACB = 115°

Explanation:

A full circle measures 360°: 92 + (4x+15) + (6x+3) = 360

10x + 110 = 360

10x = 250

x = 25

Central angles have the same measure as the intercepted arc:

ACB = 4x + 15 = 4(25) + 15 = 115°
