7 hrs

Step-by-step explanation:

the amount he made / the amount he worked

aka 5.25/7.75 --> 7

16.24°

Step-by-step explanation:

Are you trying to find the angle of depression from the camera to the cashier?

Assume that the camera is 2.24 m high and the cashier is 7.69 m away.

1. Angle of elevation from cashier

tanθ = 2.24/7.69 = 0.2913

θ = arctan(0.2913) = 16.24°  

2. Angle of depression from camera

∠ of depression = ∠ of elevation = 16.24°
