Question

A quadrilateral has angles that measure 72°,98°, and 65º.

What is the measure of the fourth angle?

Answer 1

125°

Explanation:

The angles in a qadrilateral always adds up to 360° so to get the fourth angle, you add the angles given and subtract it from 360°

72°+98°+65°+x = 360°

235°+ x = 360°

x = 360°-235°

x = 125°
