Answer 8

I:

find x and y. using the 74 degree as your reference angle,

tan(47) = opposite/adjacent = y/4
cos(47) = adjacent/hypotenuse = 4/x

K: similar logic as before

tan(38) = y/30
cos(38) = 30/x

L: this one has an extra step because you need the hypotenuse of the lower triangle to be able to solve for the upper triangle

tan(76) = 29/x

you can use the pythagorean theorem (c^2 = x^2 + 29^2) to get the hypotenuse of the small triangle. let's call that hypotenuse c.

solving the upper triangle:

sin(y) = opposite/hypotenuse = c/34

solve for y, using arcsin to eliminate the sin on the left side.
