The measure of AOC is 93



what is the measure of AOB

A.30
B.93
C.45
D.63

Answer 1

63

Explanation:

∠AOB + ∠BOC = ∠AOC

2x + 3 + x = 93

Combine like terms.

3x + 3 = 93

Subtract 3 from both sides

3x = 93 -3

3x = 90

Divide both sides by 3

x = 90/3

x = 30

∠AOB = 2x + 3

= 2*30 +3

= 60 +3

= 63
