Question

The sum of the first two angles of a triangle is 108° and the sum of the last two angles is 132° .Find all the three angles of the triangle.

Answer 1

The first two angles is 108°

The sum of the last two angles is 132°

Then, All the three angles of the triangle is x°

Now , 108° + 132° + x° = 360°

240° + x° = 360°

x° = 360° - 240°

x° = 120°

So, All the three angles of the triangle is 120°
