Question

In AKLM, 1 = 48 inches, _K=55° and L=46°. Find the length of k, to the nearest
inch.

Answer 1

We have a KLM triangle which as l = 48 in, the angle opposed to K = 55° and the angle opposed to L = 46°.

For this triangle, we have the following relation:

k^2 = l^2+m^2-2*l*m*cos 55°

Without m, we can't find k
