If the least value the variable k and be is 12, which of the following inequalities best shows all the possible values of k? PLS HURRY

k < 12

k > 12

k ≤ 12

k ≥ 12

(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.

1. are the triangles similar and if so why? what is the value of x? show your work.
