Question

In figure, the bisectors of angleA and angle B meet at
P. If angleC = 100°, angleD = 50°, find angleAPB.​

Answer 1

Answer:

80 degree

Step-by-step explanation:

x+y=200/2

x+y=100

Now in triangle PAB;

angle PAB+angle PBA+angle APB=180

x+y+ angle P=180

100+angle P=180 (Since x+y=100)

angle P=180-100

angle P=80
