Find the value of x. Round the length to nearest tenth.
Lady_Fox [76]

From the law of sines, we have

l = h\sin(\theta) = h\cos(\alpha)

where l is the leg we're interested in, h is the hypothenuse, \theta is the angle opposite to l, and \alpha is the angle between l and h.

So, in the first case, we can use

x = 15\sin(35) \approx 8.6

And in the second excercise, we use

x = 11\cos(44) \approx 7.6
