Question

A quadrilateral has angles that measure 44°, 89°, and 127°.

What is the measure of the fourth angle?

°

Answer 1

100°

Explanation:

Total angle measure of a quadrilateral is 360°

Add all the angles first.

44° + 89° + 127° = 260°

Quadrilateral has only four angle measures. And you need to find the fourth angle so,

360° - 260° = 100°

The fourth angle is measured 100°

Answer 2

100°

Explanation:

The sum of angles in a quadrilateral is 360°, so the missing angle has measure ...

360° -44° -89° -127° = 100°
