Answer: z = 7
Step-by-step explanation:
I'm assuming that they are perpendicular, but to be safe I'll say they are supplementary.
180 = 7x - 248 + x + 44
180 = 8x - 204
384 = 8x
/8 /8
48 = x
180 = 2y + 50 + 5y - 17
180 = 7y + 33
147 = 7y
/7 /7
21 = y
Therefore x = 48 and y = 21. If I made any errors please say so and don't report me :3
I think your answer is 90
