Question

In an isosceles triangle , the vertical angle is 15 degree greater than each of its base angles . Find all the angles of the triangle.
(Please anybody answer this question immediately).

Answer 1

Let the base angles be x

By angle sum property of Δ ,

x + x + x + 15 = 180

==> 3 x + 15 = 180

==> 3 x = 165

==> x = 165/3

==> x = 55

The angles are x , x , x + 15

==> 55 , 55 , 55 + 15

==> 55, 55 , 70

The angles are 55° , 55° and 70°

Hope it helps :)
