Question

please answer these questions in solution​

Answer 1

Step-by-step explanation:

let the vertical angle be 'x'

so base angle=x+27°

and the other base angle will also be = x+27°

after addition, x+x+27°+x+27°=180°.  [angle sum property]

3x+54°=180°.

3x=180°-54°

3x=126°

x=42°.

Therefore, all the angles are 42°,69°,69°.
