Question

solve this problem please .

Answer 1

b)105° is correct ans

Answer 2

Angle ADC = Angle ABC = 50°

& Angle BCD = Angle BAD = 100°

BP is the angle bisector of angle ABC

therefore, angle PBA = 50°/2 = 25°

AP is the angle bisector of angle DAB

therefore, angle PAB = 100°/2 = 50°

ABP is a triangle,

Angle PBA = 25°

Angle PAB = 50°

Sum of all the sides of a triangle =180°

therefore,

angle APB= 180°-(angle PBA+angle PAB)

=180°-(25°+50°). =180°-75°. = 105°

Answer - 105° (Option b)
