A ladder on a fire engine can be extended to maximum length of 20 m when elevated to its maximum angle 70dgree . the base of the ladder is mounted on the truck 2m above the ground . how high above the ground will the ladder reach?

The reach of the ladder is the 20 * sin70 + 2m of the truck.
20 * sin70 + 2= 20,8 m
