    From the problem definition, we have a triangle with one leg that's 2 m long, and the opposite angle is 70 degrees. What we want to know is the length of the hypotenuse (the part of the tree that fell down) so we can add it to the standing two meters for the total original height So, using some basic trig: H*sin(70) = 2m so H = 2/sin(70) so the total height was 2 + 2/sin(70)
