Answer:
30) x=124
31) x=72
Step-by-step explanation:
30 Explanation: The shape has a total of 720 degrees since it is a hexagon. There are two right angles you can subtract 180 from the 720 which leaves you with 540. You know with the rest of the information can combine the remaining angles and make the equation 4x+44=540. You then get x=124.
31 Explanation: here is a total of 540 degrees in the shape. Since the angles are all congruent you 540/5=108. Since you need x you need to do x+108=180. This means x=72.
