Answer 2

☆ Solution ☆

Given :-

• An isosceles triangle, each base angle is seven times of its vertical angle.

To Find :-

• All the angles of the triangle .

Step-by-Step-Explaination :-

Let the vertical angle be x

Both the base angle be 7x

Now,

According to the Question

=> 7x + 7x + x = 180°

=> 15x = 180°

=> x = $\frac{180}{15}$

=> x = 12

Thus,

Each vertical angle = 12

Base angle = 7x = 7 × 12

= 84

=> 7x = 7 × 12

=> 84
