Lines jk, kl, and lj are all tangent to circle o. the diagram is not drawn to scale.

if ja = 10, al = 23 and ck = 9, what is the perimeter of triangle jkl?

a. 84
b. 66
c. 42
d. 38

is the answer 84? explain how you got the answer.

(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.

Answer this question! 30 points and brainliest! only if you know the answer.
