Answer:
they are supplementary angles since they add up to 180
2x + 10 = 90 is our equation.
2x (x, the amount of baskets he made)
10 (the original bonus)
90 (total points)
Subtract 10 from both sides to get 2x by itself.
2x = 80
Divide by 2 to get x.
x = 40.
Nick made 40 baskets.
This would be like
1=6 2=12 3=18 4=24
putting this in a graph this would look like
1 2 3 4
6 12 16 24
