Answer 1

Answer:

(A) 50°

Step-by-step explanation:

Given that O is the centre of the circle

⇒ OA = OB = radius

⇒ It is an isosceles triangle

Find ∠ABO:

△AOB is an isosceles triangle

⇒ ∠ABO = (180 - 100) ÷ 2

⇒ ∠ABO =  40°

Given that PQ is a tangent to the circle

⇒ ∠OBP is a 90°

Find ∠ABP:

∠ABP = 90 - 40 = 50°
