what am I doing wrong? C++

L Tree Height ACTIVITY Simple geometry can compute the height of an object from the object's shadow length and shad tan(angleElevation)- treeHeight/ shadowLength 1. Using simple algebra, rearrange that equation to solve for treeHeight 2. Write a statement to assign treeHeight with the height calculated from an expression using angleElevation and shadowLength.
