230°
A​

Answer 1

Answer:

Step-by-step explanation:

In

∆ABC

∠ABC + ∠ABC + ∠BAC = 180o

(Because sum of a triangle)

69o + 31o + ∠BAC = 180o

∠BAC = 180o – 100o

∠BAC = 80o

Since ∠BAC and ∠BAD are in the same

Segment.

∠BAD = xo = 80o

Given ∠CPB = 120o , ∠ACP = 70o

To find, xo i,e., ∠PBD

Reflex ∠CPB = ∠BPO + ∠CPA1200 = ∠BPD + ∠BPD

(BPD = CPA are vertically opposite ∠s)
