Here, the height of the tree is labeled  " t " .

Since the tree makes a  90º  angle with the ground, we can say...

tan 58º  =  t / 20                                 Multiply both sides of the equation by  20  .

20 tan 58º  =  t                                   Put this into a calculator to get that...

32.007  m  ≈  t
