Angle x is (2n + 12)°, and angle y is (3n + 18)° . find the measure of angle x.

note: not drawn to scale.
a) 24°
b) 30°
c) 72°
d) 108

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.
