Q:

A pentagon has angle measures of 102°, 100°, 115° and 110°. What must the fifth angle measure?

Accepted Solution

A:
Pentagon angles add up to 540°. So we subtract all angles above from 540° to find the fifth angle.

540 - 102- 100 - 115 - 110= 113°

ANSWER:
The fifth angle measures 113°.

Hope this helps! :)
