Answer:

D. 145°

Explanation:

Since Angles ∠CBA and ∠DBE are vertically opposite

Then

m∠CBA = m∠DBE

Then

2x + 21 = 5x

Then

3x = 21

Then

x = 7

Therefore

m∠DBE = 5x = 5 × 7 = 35

…………………………………………………

Since Angles ∠DBE and ∠ABE are supplementary

Then

m∠ABE = 180 - m∠DBE

= 180 - 35

= 145°
