Cos Z = 32/40 => Z= cos-¹(32/40) =>
sin Z = sin (cos-¹(32/40)) = 3/5
Plug the given x and y values (x, y) into the equations and solve
It look like the second equation is the answer.
Answer:
(x, y) ⇒ (½x, ½y)
(x, y) ⇒ (x + 7, y + 7)
Step-by-step explanation:
each x value of P'Q'R' is half of the x value for PQR
each y value of P'Q'R' is half of the y value for PQR
each x value of P"Q"R" is seven units to the right of the x value for P'Q'R'
each y value of P"Q"R" is seven units above the y value for P'Q'R'
