Problem

A triangle has angle measurements of 28°, 45°, and 95°. What kind of triangle is it ?

Hint

The given measurements belong to the Obtuse angle.

Step

An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees.

Step

In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°.

Step

So, it is an Obtuse angle triangle.
