Part A: (5 points) Rewrite cos(135 +30) using the sum identity formula, in Radians. Substitute the values from the Unit Circle into the expression. Without converting to decimals, simplify the expression (keep, but simplify roots, fractions and ). Be sure to include all necessary work. Don't forget to rationalize the denominator, whenever necessary. Part B: (5 points) Rewrite 11T sin (ST-II) 3 6 using the difference identity formula, in degrees. Substitute the values from the Unit Circle into the expression. Without converting to decimals, simplify the expression (keep, but simplify roots, fractions and T). Be sure to include all necessary work. Don't forget to rationalize the denominator, whenever necessary.
