Answer:
x = 64
Step-by-step explanation:
The sum of interior angles of a pentagon is 540°, so you have ...
90° +2x° +84° +2x° +110° = 540°
4x = 256 . . . . collect terms, subtract 284°, and divide by °
x = 64 . . . . . . .divide by 4
540 degrees in a pentagon.
90 + 110 + 84 + 2x + 2x = 540
284 + 4x = 540
4x = 256
