Answer:
C.
Step-by-step explanation:
I believe they are called the "Legs." They are also referred to as the opposite and adjacent sides. :)
Add 3x and 7x because they’re on the same and when you added it you’ll get 10x and than do 32+-22 and you’ll get 10 because 32-22 is 10 and you subtract the 10 to 180 and you’ll get 10x=170 and divide 170 by 10x to get x by itself when you divided you’ll get x=17 and that’s the answer.
