Question

The sum of mZAOB and mZBOC IS 128º. Find the measure of ZBOC.

Answer 1

128 - 33 = 95
Answer C. 95

Answer 2

Answer:

C

Step-by-step explanation:

m∠AOB + m∠BOC = m∠AOC

m∠AOB is an acute angle. Because it's 33°, less than 90°

m∠AOC is 128° , so it's an obsute angle . Because it's more than 90°, less than 180°

To find m∠BOC , just subtract m∠AOB from m∠AOC

128° = 33° + m∠BOC

m∠BOC = 128° - 33°

m∠BOC = 95°

Option C

So, m∠BOC is an obsute angle . Because it's more than 90°, less than 180°

more about angles: Right angle = exactly 90° , Straight angle = exactly 180°,

Full angle = exactly 360°
