1. If θ is the angle between the base and slope of a skate ramp, then the slope of the skate ramp becomes the hypotenuse of a right triangle. What is the length of the slope of the skate ramp if the sinθ=8/17 and the cosθ=15/17 if the sum of the horizontal base and the height of the ramp is 100ft?
2. Find the positive measure of θ (rounded to the nearest degree) if the sinθ=-0.7234, and the terminal side of θ lies in quadrant III.
3. Find the positive measure of θ (rounded to the nearest degree) if the sinθ=.0274, and the terminal side of θ lies in quadrant II.
4. Find the positive measure of θ (rounded to the nearest degree) if the cosθ=0.2134, and the terminal side of θ lies in quadrant IV.
5. Find the positive measure of θ (rounded to the nearest degree) if the cosθ=-0.8674, and the terminal side of θ lies in quadrant III.
