The angle of depression from the top of the school to the base of the flag pole in front of the school is 50° . If the flag pole is 35 feet from the base of the school, find the height of the school. A) 38.4 ft B) 39.2 ft C) 39.8 ft D) 40.5 ft E) 41.7 ft

41.7ft

Step-by-step explanation:

Tan50°=h/35

35×tan50=h

h=41.71

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
