Question

Each baise angle of an isosteles tranquis
5 more than its vertical angle. Find earn
angle of the triangle​

Answer 1

Answer:

Consider the vertical angle of the isosceles triangle =x

∘

Here each base angle=x+15

∘

In a triangle

x+15

∘

+x+15

∘

+x=180

∘

By further calculation

3x+30

∘

=180

∘

3x=180–30=150

∘

x=150/3=50

∘

Therefore, vertical angle =50

∘

and each base angle =50+15=65
