Angle PQR is formed by segments PQ and QR on the following coordinate grid: Angle PQR is rotated 90 degrees counterclockwise about the origin to form angle P'Q'R'. Which statement shows the measure of angle P'Q'R'?

m∠P'Q'R' = 90 degrees
m∠P'Q'R' = 180 degrees
m∠P'Q'R' = m∠PQR
m∠P'Q'R' = 2 ⋅ m∠PQR

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
