The trig ratio that we would use is
sin \theta = (opp. leg)/(hyp)
Plugging in the values we get the following equation

sin20^o= (15)/(h)
Looks tricky but you just need to interchange sin 20 and h

h= (15)/(sin20^o)
You probably need to make sure your calculator is in degree mode.
hypotenuse is approximately 43.86
