If you wanna solve for x, you have to try to get x by itself, right?
so,
<span>
tan36°= 12/x </span>
---> multiply both sides by x
<span>
xtan36 = 12 </span>
---> now, solve for x by dividing both sides by tan36
so, you need to do 12/tan36
<span>so when you plug that into your calc, you get: 16.5165... which rounds to 16.52
