Question

each of the two equal angles of a triangle is twice the third angle find the angles of the triangle

Answer 1

Answer:

∠1 = 36°

∠2 = 72°

∠3 = 72°

Step-by-step explanation:

Let the third angle be 'x'.

∴ Other two angles will be '2x'.

∠1 + ∠2 + ∠3 = 180° (Angle Sum Property of Triangle)

⇒ x + 2x + 2x = 180°

⇒ 5x = 180°

⇒ x = 180° / 5 = 36°

∴ ∠1 = x = 36°

∠2 = 72°

∠3 = 72°
