Question

In isosceles triangle, the base angle is twice as large as vertex angle.find the angle of the triangle.

Answer 1

Answer:---

Since , it is an isosceles Δ the base angles will be equal

Let the base angles be x

Vertex angle be 2x

Sum of angles = 180°( angle sum property of Δ)

x+x+2x=180

4x=180

x=180/4

x=45°

Therefore ,base angles are 45° eack and vertex angle is 90°
