Answer:
angle c is inscribed in circle 0
AB is a diameter of (71)/2
Verified answer
Step-by-step explanation:
Here,
∠A= 71°
And, ∠C=90°(being angle made in semi-circle is a right angle)
Then,
∠A + ∠B + ∠C = 180°(sum of interior angles of a triangle is 180°)
or, 71° + ∠B + 90° = 180°
or, 161° + ∠B = 180°
or, ∠B = 180°-161°
i.e. ∠B = 19°
