Question

A triangle has one angle that measures 39 degrees, one angle that measures 104 degrees, and one angle that measures 37 degrees. What kind of triangle is it? *

Answer 1

Answer: Obtuse triangle

Explanation:

An obtuse triangle is a kind of triangle that has one of its three angles to be greater than 90 degrees but less than 180 degrees.

For instance: Angle ABC + Angle BAC + Angle ACB = 180° ( where Angle ABC = 39°, Angle BAC 104°, and Angle ACB = 37°)

On the other hand, a right-angled triangle has 90° as one of its angles, while acute-angled triangle has all its three angles less than 90°

Thus, since one of its angles in the triangle is 109° it is a obtuse triangle.
