Answer:

obtuse

Explanation:

The largest angle is more than 90°, so the triangle is called an "obtuse" triangle.

Here are the classifications based on the measure of the largest angle:

< 90° -- acute triangle

= 90° -- right triangle

> 90° -- obtuse triangle . . . . . like the one in this problem statement
