Question

In the adjacent figure, the bisectors of ∠A and ∠B meet at point P. If ∠C = 90° and ∠D = 70° then measure of ∠APB is​

Answer 1

⇒∠APB=80

Step-by-step explanation:

60 ∘ +100∘ +∠A+∠B=360 ∘

⇒∠A+∠B=200 ∘

⇒ 2∠A+∠B

=100 ∘

⇒∠BAP+∠ABP=100 ∘

But ∠BAP+∠ABP+∠APB=180 ∘

⇒∠APB=80 ∘

Answer 2

Answer:

APB 160

Step-by-step explanation:

APB=A+B

APB=9O+70

APB =160
