Question

In the given figure, PAQ is the tangent. BC is the diameter of the circle. If ∠BAQ = 60°, find angle ABC.

• A. 25
• B. 30
• C. 45
• D. 60

Answer 1

Answer:

B. 30

Read Explanation:

Therefore, in the given figure- ∠BAQ = ∠ACB = 60° (By alternate segment theorem) Since BC is diameter, ∠BAC = 90° ∠ABC = 180°−(90°+60°) = 30°
