PLZ HELP ME
I appreciate any help, especially if you can show me how you got the answer

Some calculus, a little better than the usual slopes and distances.

L'Hopital applies because the numerator is sin 0 = 0 and the denominator is ln(2 e^0 - 1) = ln 1 = 0 so we have 0/0, case number one for L'Hopital.

Evaluating the latter form at t=0 we get

C  1/2

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
