Write a list of steps that are needed to find the measure of angle B.
A measures 72 degrees and C measures 113.
What does B measure?! Please help!
to find the missing angle the steps I did 180-113=67 180-72=108 and then 108-67=41 so ∠b=41
A + B + C = 180.
72 + B + (180-113) = 180,
72 + B + 67 = 180,
B = 180 - 72 - 67 = 41o.
