Question

in an isosceles triangle the vertex angle is 4 times that of both the base angles .found the angle of the triangles
​

Answer 1

answer

30,30,120

Step-by-step explanation:

in Isosceles triangle, both base Angeles are same.

let the base angle be = x

vertex angle = 4x

then,

$x + x + 4x = 180 \\ 6x = 180 \\ x = 30 \\ \\ 4x = 4 \times 30 = 120$

so the angles are 30,30,120
