Question

In the figure PB is the tangent to a circle with centre A If ABP =40° then PAB​

Answer 1

Step-by-step explanation:

Given:

PB is the tangent to a circle with centre A

ABP=40°

Since point of contact always perpendicular,

Therefore, APB= 90°

Now,

APB+ABP+PAB = 180°

=40°+90°+PAB=180°

=130°+PAB=180°

PAB=180°-130°

PAB=50°
