Question

plss solve it 1st question..​

Answer 1

Answer:

x=30°

y=60°

z=120°

Step-by-step explanation:

AOC+COE+EOB=180°(linear pair)

2x+90°+x=180°

3x=180°-90°

3x=90°

x=90°/3

x=30°

COE+EOB+BOD=180°(linear pair)

90°+30°+y=180°

120°+y=180°

y=180°-120°

y=60°

AOD+DOB=180°(linear pair)

z+60°=180°

z=180°-60°

z=120°

Hence,x=30°

y=60°

z=120°
