Sum of interior angles is (n - 2)180°, where n is the number of sides
The interior angles of FLIPS add to 3(180°)
110 + 20x + 95 + 50x + 100 = 540
Can you solve for x?

To increase your confidence - were all of the operations you performed correct? If so, then your solution is correct!
(And that's the solution I got)
