The trig ratio that we would use is [tex]sin \theta = \frac{opp. leg}{hyp} [/tex]
Plugging in the values we get the following equation
[tex]sin20^o= \frac{15}{h} [/tex]
Looks tricky but you just need to interchange sin 20 and h
[tex]h= \frac{15}{sin20^o} [/tex]
You probably need to make sure your calculator is in degree mode.
hypotenuse is approximately 43.86
