Question

A triangle has angles that measure 108°, 23°, and 49°. What kind of triangle is it
Anybody know?

Answer 1

There are several classifications: equilateral, isosceles, scalene; acute, obtuse, right.
Use the information that no two angles are equal and one angle is greater than 90 degrees to eliminate choices.
E.g. an equilateral triangle has all 60 degree angles, so that's not it. It isn't a right triangle because it has no 90 degree angle. etc.
