The 3r would be the independent variable and m=30 is the dependent variable. Double check the answer though.
The answer is - 8x^2y+6xy
Answer: 39.3 inches
Step-by-step explanation:
Let x represent the length of base of ramp.
We have been given that a skateboarding ramp is 12 in high and rises at an angle of 17 degrees. We are asked to find the base of the skateboard.
The height of ramp, the base of ramp and angle of elevation make a right triangle with ground, where, 12 inch is opposite side and base of ramp is adjacent side of angle of elevation.
Therefore, the base of ramp is 39.3 inches long.
Answer:
I believe is A.
Step-by-step explanation:
