Question

The base angle of an isosceles triangle is 15º more than its vertical angle. Find its
each angle.​

Answer 1

Answer:

sum of angles of ∆ = 180°

let side be X cm

By isosceles triangle theorem

opposite sides of isosceles triangle are congruent

and

from these we can sat that , angles opposite to congruent sides are congruent

and. therefore ,

15°+x°+x°= 180°

15°+2x°= 180°

2x°=180°-15°

2x= 165

X= 165/2

solve further you can do it....
