8. Given tan 0 = -3/2 , 0 Ell, find sin 0 and cos 0. 9. Find sin(arctan ;). 10. Find two vertical asymptotes for the function y = 2tan(x + ).6. Finding the height of a mountain. A surveyer uses an instrument called a theodolite to measure the angle of elevation between ground level and the top of a mountain. At one point the angle of elevation is measured to be 420. A half kilometer farther from the base of the mountain, the angle of elevation is measured to be 350. How high is the mountain? h 1350 D' 0.5kin 7. Assume a point on the terminal side of the angle 0 is P(2, -3), find sin 0
