Question

If the measures of the angles of a pentagon are 150 °, 27 °, 124 °, and 156 °, what is the measure of the last angle?

Answer 1

The sum of internal angles is equal to 540 degrees. Therefore if we subtract the given angles from 540 we should find the missing one.

`A=540-150-27-124-156=83`

The missing angle is equal to 83 degrees.
