Rectangle PQRS is rotated 90° clockwise about the origin.
5x
What are the coordinates of R'?

90 degrees clockwise from where it started

Step-by-step explanation:

If you rotate the rectangle clockwise 90 degrees four times it ends up where it started so rotate it one more time and you should have your answer, it should be the same as when you rotate it 90 degrees once

(-4,1)

Step-by-step explanation:

I just grabbed a piece of paper and traced a cross on the origin and the image/ points. I labelled the points too. then i turned 90 degrees clockwise (where the line that was originally at the top of the cross was pointing right) and looked to see where the point resembling r landed on that part of the graph

plus i got it right on the test     :)

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
