Question

75. In the adjoining figure, the bisectors of Angle A and Angle B meet in a point P. If Angle C = 100°,
Angle D = 60°. Find the measure of Angle APB.

​

Answer 1

60°+100°+angleA+angleB=360°

AngleA+angleB=200°

1by2 angleA+1by2 angleB=100°

Therefore,

AngleBAP+angleABP+angleAPB=180°

100°+angleAPB=180°

angleAPB=180°-100°

angleAPB=80°

ANSWER:80
