Question

Each of the two equal angles of a triangle is twice the third angle. Find the angles of the
triangle.
​

Answer 1

Answer:

let the angle be x

the two equal angles are twice the third angle

so one angle is x

and other 2 is 2x

the sum of the measure of the angle of a triangle is 180⁰ (degree)

x + 2x + 2x = 180⁰

5x = 180⁰

x = 36⁰

and the rest two angles:-

2x = 2 × 36 = 72

so the angles of a triangle are 36⁰,72⁰,72⁰
