The measure of the angles of triangle abc are given by the expressions in the table. angle-measure a-48 degrees b-(6x-28)degrees c- (2x) degrees find the value of x. then find the measures of angles b and c. enter your answers in the boxes. x= m m

(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.

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9
