Answer:
A :)
Step-by-step explanation:
I believe the answer is A because on a line it equals 180 and because the angle of 8 is equal to 171, you still need to find 9 more degrees. You set 2x-33 equal to 9 and solve as a two step equation, and get the answer 21. Hope this helps :)
Answer:
4x^10y^8
Step-by-step explanation:
Get gud at math you newb
It is B because have you do 160+77-x=180 you would add the like terms 160+77=237 and then subtract 180 from 237 and you get 57 for x and when you plug that in 160+77-57 77-57=20 and 20 plus 160 is 180 so The answer is B)No of these
