Pls help it’s for math pls pls help

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?

Use the elimination method to solve the systems of equations.choose the correct ordered pair. 7x+4y=39

Pls brainliest will be awarded if answer is correct
