Question

ONE SIDE OF a triangle has been produced. Find all the angles of the triangle in each case. ​

Answer 1

Answer:

The Exterior angle Property of a triangle states that the sum of the two interior opposite angles of the triangle equals to the exterior angle.

50° + x° = 125°

x° = 125° - 50°

x = 75°

∠C = z°

z° + 125° = 180° (Linear Pair)

z° = 180° - 125°

z° = 55°

Hence ∠A = 50°

∠B = 75°

∠C = 55°
