3.a robot is on the surface of mars. the angle of depression from a camera in the robot to a rock on the surface of mars is 13.78°. the camera is 184.0 cm above the surface. how far is the camera from the rock? (round to the nearest tenth as needed.)

750.25 cm

Explanation:

θ = 13.78°, h = 184 cm

Let the distance between rock and camera is d.

Tan θ = h / d

tan 13.78 = 184 / d

d = 750.25 cm

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
