3. Convert the angle A = 126 17'38" in degrees, minutes, and second format to a decimal degree angle. Please round your answer to the nearest ten-thousandth (so your answer will have the format 126.7785 - although this is not the correct answer ! ) 4. Find four standard position angles between 0 and 360, one in each quadrant, which each have reference angle 15. 5. Convert the angle B = 144 to radians. (your final exact answer should be a fraction involving 7 ) 6. Find the exact value of sin(tan -1(-3/7)). (your final exact answer should be a fraction involving a square root) 7. Use a calculator to evaluate each expression. Write all answers rounded to the nearest hundredth. ( if your answer is an angle measured in degrees, be sure to include the degree symbol . ! ) (Be careful of units - an angle is assumed to be in radians unless it is followed by the degree symbol . ! ) (a) csc(-0.8) (b) sin (-0.8) (c) cot 47
