Question

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

Answer 1

Let the third angle be A
So each of the two angles is 2A
So sum of all three angles is 2A+2A+A=5A=180
So A=180/5=36
So the angles are 36,72,72

Answer 2

Let the third angle be x

Therefore each equal angle= 2x

2x+2x+x= 180° (Angle sum property of a triangle)

5x= 180°

x= 180°/5

x= 36°

Answer: The first angle is 2x= 2(36)= 72°

The second angle=first angle= 72°

The third angle= 36°

Hope it helps! :)
