Question

Height of a hot air balloon. As a hot air balloon began to ride, the ground crew drove 1.2mi to an observation station. The initial observation from the station estimated the angle between the ground and the line of sight to the balloon to be 30. Approximately how high was the balloon at that point

Answer 1

0.7 mile high

Explanation:

tan 30 = height /1.2

so height =1.2 *tan30 = 1.2*0.58 = 0.7
