Simple geometry can compute the height of an object from the the object's shadow length and shadow angle using the formula: tan(angleelevation) = treeheight / shadowlength. given the shadow length and angle of elevation, compute the tree height. sample program: #include #include int main(void) { double treeheight = 0.0; double shadowlength = 0.0; double angleelevation = 0.0; angleelevation = 0.11693706; // 0.11693706 radians = 6.7 degrees shadowlength = 17.5; printf("tree height: %lf\n", treeheight); return 0; }
