45 DEGREE

Answer 2

Answer:  (d) 45°

Step-by-step explanation:

Since BOC is a diameter,

∠BAC = 90° (angle made by a diameter is 90° at circumference)

Since AB = AC,  => ∠ABC = ∠ACB = x        (assumed)

=> 90 + x + x = 180°  (ASP of a triangle)

=>  2x = 180 - 90

=> x = 90 / 2

=> x = 45°

Therefore the answer is (d) 45°
