What is meant by an angle of 75.0° with the vertical. (1 Viewer)

? could some one explain ty ^^
A car travels due east with a speed of 55.0 km/h. Raindrops are falling at a constant speed vertically with respect to the Earth. The traces of the rain on the side windows of the car make an angle of 75.0° with the vertical. Find the velocity of the rain with respect to the following reference frames.

 

[pqd123]

the angle with the vertical is the angle that the rain would be making with a line going straight down

 

[Pwnage101]

Draw a vertical line. A (straight, intersecting) line that is 75 degrees from that. either way.

I'm guessing an angle of 75' with the vetical would mean an angle of 15' with the horizontal

so vertical u = u sin15
and horizontal v = u cos 15
