Answer: 24
========================================================
Step-by-step explanation:
Focus on the largest triangle. The two known interior angles are 41 and 94. The missing interior angle, let's call it y, adds to the others to get a sum of 180.
This means we can say the following:
41+94+y = 180
135+y = 180
y = 180-135
y = 45
-------
Now move your attention to the smaller triangle off to the right side.
It has interior angles of 111, x and y.
x+y+111 = 180
x+45+111 = 180
x+156 = 180
x = 180-156
x = 24
