Question

In an isosceles triangle the base are equal and vertex angles is twice of each base angle. Find the measure of the angles of the triangle.

Answer 1

here we let that base angle is x
then vertex angle will be 2x and total of angles of a triangle is 180
then equation will be
x +x+2x=180
4x=180
x=180/4=45°
then base angle is 45° and vertex angle is 90°

Answer 2

Hello

Let the base be x

Then the vertex be 2x

Acc. to .Que.

x+x+2x=180(Sum of all angle of triangle)

4x=180

x=180/4

x=45

Hence the base is 45 degree and vertex is 90 degree.
