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°
