Question

Calculate the value of x

Answer 1

Answer:

x = 64

Step-by-step explanation:

540 degrees in a pentagon.

90 + 110 + 84 + 2x + 2x = 540

284 + 4x = 540

4x = 256

x = 64

Answer 2

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
