(a) Find the measure of the least positive angle that is coterminal with A =-48. Then find the measure of the negative angle that is coterminal with A and nearest to its original measure. (b) Find the measure in radians of the least positive angle that is 16x coterminal with the given angle B (Type an exact answer in terms of x) A satellite photographs a path on the surface of the Earth that is 2500 miles wide. Find the central angle that intercepts an arc 2500 miles on the surface of the Earth (radius 3950 miles) Sketch the given angle 0 in standard position and find its reference angles in degrees and radians. Use reference angles to find the exact value of the expression sind and cose. Do not use a calculator. (a)0 = (b)0 6. 10x (c)e: 3. (d) 235 Find the exact value of cos a, given that sin(a) = and a is in quadrant IV.
