What is the image of the point (1,-4) after a rotation of 270 ∘ counterclockwise about the origin?

We know thatin the right trianglecos 35=adjacent side angle 35/hypotenuseadjacent side angle > > the height, of the sail  > 8 msocos 35=h/> h=8*cos 35remember thatsec x=1/cos xsocos 35=1/sec 35substituteh=8*(1/sec > h=8/sec 35the answer is the optiond.)  8 divided by sec 35 degrees
