Sum of interior angles of a quadrilateral is 360°
- 110° + 130° + x + x - 3° = 360°
- 2x = 360° - 237°
- 2x = 123°
- x = 61.5°

Sum of interior angles of a hexagon is 180°*(6 - 2) = 720°
- 2*90° + 2x + 2(x + 22°) = 720°
- 90° + x + x + 22° = 360°
- 2x = 360° - 112°
- 2x = 248°
- x = 124°

Interior angles of a given pentagon are all marked as congruent, so the exterior angles are congruent too.
Sum of exterior angles is 360°.

Answer: the fraction -8/117</h3>
----------------
First, convert to an improper fraction
3 & 1/4 = 3 + (1/4)
3 & 1/4 = (12/4) + (1/4)
3 & 1/4 = 13/4
The mixed number 3&1/4 turns into the improper fraction 13/4
---------------
-2/9 divided by (3&1/4) = -2/9 divided by 13/4
To divide two fractions, you flip the second one and then you multiply
"-2/9 divided by 13/4" turns into "-2/9 times 4/13" after this happens
Then you multiply straight across. The numerators stick together. The denominators stick together.
numerators: -2*4 = -8
denominators: 9*13 = 117
We end up with the fraction -8/117
This cannot be reduced as there are no common factors (other than 1) between 8 and 117.
