Respuesta :

if you wanna solve for x, you have to try to get x by itself, right? 
so, 

tan36°= 12/x 

---> multiply both sides by x 

xtan36 = 12 

---> now, solve for x by dividing both sides by tan36 

so, you need to do 12/tan36 

so when you plug that into your calc, you get: 16.5165... which rounds to 16.52
