Write a function rule for: 10 more than two times x is y

(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.

Plz ( true - false) all triangles have interior angles whose measure sum to 90.

The anwser cause i do not understand just plez
