four interior angles of a pentagon measure 156°, 72°, 98°, and 87°. What is the measure of the final interior angle

Answer 1

Hello!

The sum of all interior angles of a pentagon is 540°. To find the missing angle we subtract all of the angles we have from 540.

540-156-72-98-87=127

The measure of the final interior angle is 127°.

I hope this helps!
