Both add up to 90 degrees as they are complimentary angles:
5x + 3x + 2 = 90
8x + 2 = 90
8x + 2(-2) = 90(-2)
8x = 88
8x/8 = 88/8
x = 11
39 degrees. All angles must add up to 180 and the two acute angles equal each other because of the type of triangle it is!
Answer: x = 21
Step-by-step explanation:

Answer:
90
Step-by-step explanation:
x•y-z²
x=9,y=14,z=6
9 • 14 - 6²
126-36=90
The U in the upper right corner stands for the universal set.
As universal set defined the set containing all objects or elements and of which all other sets are subsets. So, the answer is B.
