109°

Step-by-step explanation:

To figure this problem out, we should start with the rule that a pentagon's angles add up to 540°. The angles in the given pentagon are 121°, 102°, 108° and 100°. To find x, we need to make sure all 5 angles add up to 540.

121°+ 102°+108° +100°+x=540°

If you add those four given angles, you get 431°.

540° - 431° = 109°

you probably already have the answer but anyways it's b. 15.0
