Answer:
D
Step-by-step explanation:
The term "supplementary" means that the two angles add up to 180°, which means we can write an equation:
17x + x = 180
18x = 180
÷ 18
x = 10
And now you can multiply 10 by 17, because it is 17 times the angle, to get 170° and 10° as your answer.
I hope this helps!
Yes you do need to regroup it would be 4
None of them is equivalent...
