A ramp is designed with the profile of a right triangle. The measure of one acute angle is 5 times the measure of the other acute angle. Find the measure of each acute angle. a. 18°, 72° c. 15°, 75°
b. 4.5°, 85.5° d. 9°, 81°

For 15 to 20, change the equation from y=mx+b into mx-y=-b
Example: 15) y=-5x+2 into -2=-5x-y or 2=5x+y
For 21-29, the numbers in the parenthesis are coordinates (x, y) so uh the equation y=mx+b plug in the m that is given and x and y and then solve for b to complete the equation
Ex: 21) (-8,3) m=2
Y=mx+b
3=2(3)+b
3=6+b
-3=b
So y=2x-3
Do the same to the others
