There are two things to notice that can help you:

  1. the length of the pole is h + h_2
  2. h_2 is a part of a right triangle

You can make a right triangle using the black pole as the hypotenuse, and the child’s distance from the pole and h_2 as the legs. If the hypotenuse length is r, then the h_2 leg of that triangle is rcos(72). And we know r, the hypotenuse length, is 1.65. So plug that in and now we know the value of h_2

Now we have length of pole = h + h_2. Length of pole is easy to calculate, and we have h_2. You can now solve for h
