Question

find the angles
with complete solution

Answer 1

Hiii
===========
In ∆ ABC,
angle B = 30°.........Given
Angle A= 90° ....angle subtended in semicircle

Sum of angles of ∆ is 180°
angle A + angle B + angle C = 180°
90° + 30° + angle C = 180°
120° + angle C = 180°
angle C = 180° - 120°
angle C = 60°

angle PAB = angle B = 30° ......... alternating angles

& angleTAC = angle C = 60° ....... alternating angles
