Answer:
C
Step-by-step explanation:
If you look at the two angles, one is 7x and the other is 11x, they appear to be next to each other and make a right angle, if you look at the bottom corner of them there is a square which means it is a right angle. this means that if you put 7x with 11x it would = 90
