The angle of elevation of the top of a tree from a point 100 meters from the foot of the tree is 36 degrees. How high is the tree?​

To answer this question we can think Soh Cah Toa. If we are 100 ft from the tree and at an angle of 36 degrees and we want what I call the rise we can us the Toa formula tan(36)=o/100 then manipulate algebraically until we get the following o=tan(36)(100) this give us the height (o) to be 72.65 meters

Does the problem say y=x+4?
