Question

Ok so I got the interior angles written down now I need to find the sum of the interior angles and I don't know how to do that.

Answer 1

We are to find the sum of interior angles of a triangle.

Interior angles simply means all the angles inside the triangles.

The sum of interior angles of a triangle is equal to 180 degrees, meaning that when we add all the three angles inside a triangle we must get 180 degrees.

So the sum of the interior angles of the given triangle is;

`90^0+53.13^0+36.87^0=180^0`

Moreso, this triangle is a right angled triangle because one of the angles is a 90 degrees.
