Question

In the
fig
AB is the
diameter
of the
circle, then find x​

Answer 1

50 degree is the answer of this q

Answer 2

Answer:

x = 50°

Step-by-step explanation:

In ΔABC,

∠A + ∠B + ∠C = 180°        ( Angle Sum Property )

x + 40° + 90° = 180°          

( ∵ In a triangle inscribing a semicircle the angle opposite to the diameter is equal to 90°. ∴ ∠C = 90°)

∴ x = 180° - 90° - 40°

∴ x = 50°
