Question

Find x in the given figure if m∠AOC = 124°.

Question 4 options:

A) 8

B)6

C) 7

D) 9

Answer 1

A) 8

Explanation:

Add angles AOB and BOC to get angle AOC.

Since we know the value of AOC is 124 and AOB+BOC=AO

Then (8x+25)+(6x-13)=124.

Combine like terms to get 14x+12= 124.

Solve for x by subtracting 12 from 124, then divide the answer by 14.
