In ΔJKL, \overline{JL} JL is extended through point L to point M, \text{m}\angle JKL = (3x-16)^{\circ}m∠JKL=(3x−16) ∘ , \text{m}\angle LJK = (2x+15)^{\circ}m∠LJK=(2x+15) ∘ , and \text{m}\angle KLM = (8x-19)^{\circ}m∠KLM=(8x−19) ∘ . Find \text{m}\angle LJK. m∠LJK.

(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.

The square root of 9x plus 7 plus the square rot of 2x equall to 7
