Question

8. If angle CBD = angle DBE find m angle A

Answer 1

∵∠CBD＝∠DBE
∴x＋10＝60
x＝50
∵∠A＝x＋5
∴∠A＝50＋5＝55°

Answer 2

Answer:

m∠A = 65°

Step-by-step explanation:

Because ∠CBD is congruent to ∠DBE, we can set the degree values equal to each other.

So

CBD has x + 10, DBE has 60. So:

x + 10 = 60

Subtract 10 from both sides.

x = 50

Check:

50 + 10 = 60

60 = 60

m∠A = (x + 5)° = (60 + 5)° = 65°
