Answer 1

Answer:

AOD+AOC=180°

x+42°=180°

x=180°-42°

x=138°

BOD=AOC (V.O.A)

BOD=42°

COB=AOD (V.O.A)

COB=138°

Answer 2

Answer:

Measure of angle COA - 42°

Therefore,

Measurement of angle BOD - 42°( Opposite angles are of equal measurement )

Now,

Measure of all angle is 360°

Therefore,

Measure of angle AOD and angle COB = ?

Let's assume both of these angles as 'x'

Therefore, we can say

360 = 2(42) + 2x

= 360 = 84 + 2x

= 2x = 360 - 84

= 2x = 276

= x = 138°

Therefore

Measure of angle AOD - 138°

Measure of angle BOD - 42°

Measure of angle COB - 138°
