Question

In the isosceles triangle, the vertex angle is 1/4th of each of the equal angles. Find the angles of the triangle​

Answer 1

Answer:

the angles are 80, 80, 20.

Step-by-step explanation:

Let the equal angle be x and vertical angle be x/ 4

Sum of the angles in a triangle = 180

x +x+x/4=180

4x+4x+x=180×4

9x = 180×4

x=20×4

x=80

one fourth of x=x/4=20
