Question

A triangle has angles that measure 107°, 20°, and 53°. What kind of triangle is it?

Answer 1

Scalene triangle

Explanation:

Let's first cancel out the obvious.

This is not a equilateral triangle because the angles are not equal.

Now if you draw out the triangle, you can see that the triangle is a little weird. Not at all a equilateral triangle.

It's also not a iscosles because no two angles are the same.

Thus we end up with scalene triangle.

Hope this helps!
