Question

if angle AOC = 50 then (angleAOD + angle COB) is + to ...?

a. 100
b. 130
c. 140
d. 260

Answer 1

Answer:

b is the answer 130

Step-by-step explanation:

180-50=130

Answer 2

Step-by-step explanation:

Given

AOC is a straight line

∠AOB=50°

∠AOE=90°

∠COD=25°

To find the measures of ∠BOC

∠AOB+∠BOC=180°

{Linear pairs of angle}

50 ° +∠BOC=180°

On further calculation, we get

∠BOC=180°−50°

∠BOC=130°
