Answer:

61°

Step-by-step explanation:

First, we need to find what type of shape this is. Since it has 5 sides, it's a pentagon.

Now we need to figure out the sum of all interior angles in a pentagon. The sum of all interior angles in a pentagon is 540°

We can easily solve for x now by adding all angles up.

107°+144°+138°+90°+x°=540°

479°+x°=540°

x°=61°
