-8
f(x) is y, in which x is the independent variable
when x = 5, y = -8
15^2 + 36^2 = 39^2
Your answer is 39
Take the equations and solve them. they should lead up to degrees. Then add those degrees together and subtract that answer by 360 degrees and that should be your answer.
Hope this helps
1.667
Basically divide the number by 2
The only way for you to get an answer is by doing $5.25x2=$10.5 and $3.50x3=$10.50
