Question

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

What is the measure of the fourth angle?

Answer 1

The sum of angles in a quadrilateral = 360 degrees.

Let the fourth angle be x:

Therefore: 44 + 89 + 127 + x = 360

260 + x = 360

x = 360 - 260

x = 100

x = 100°

I hope this helps.
