Question

In an isosceles triangle, the base angles are equal. If each base angle is twice of the vertex angle, what are the degree measures of the angle of the triangle

Answer 1

Step-by-step explanation:

let the vertex angle be x

base angle =2x

x+2x+2x=180°

5x=180°

x=36°

vertex angle =36°

base angle=72° each

Answer 2

Answer:

The base angles would be 72°, and the vertex angle will be 36°.

Step-by-step explanation:

We know that,

The sum of all the angles in a triangle is 180°.

So,

by considering the vertex angle as 'x';

the base angles will be-'2x' (because the base angle is twice the vertex angle)

Therefore;

=>2x+2x+x = 180°

=>5x = 180°

=>X = 180°

5

=>x = 36°

So,

vertex angle = x =36°

base angles =2x = 2×36=72°

Hope this helps
