13. Find the angle so that the beetle is exactly at the surface of the water14. How many angles in the interval?

D Question 13 3 pts In a previous exercise we discussed a water wheel of radius 15 ft which is submerged 3 ft in flowing water. A beetle is sitting on the very edge of the water wheel and we found that when the beetle made an angle of 0 with the horizontal the beetle was f(0) ft above the water where f(0) = 15 sin(0) + 12. Assuming that 0 is in radians now (the same equation still works), find the angle 0 so that the beetle is exactly at the surface of the water, so that 8x 0. Round to two decimal places. -0.93 D Question 14 3 pts How many angles in the interval [4x, 6x] satisfying the equation 7 cos (6x + - ) - 2 = 1 are in the second quadrant
