Given a 90 counterclockwise rotation find tha image of -5,7

Explanation:

A 90 ° counterclockwise rotation is a rigid transformation that transforms any point (x,y) of a figure into a point with coordinates (-y,x).

The rule is:

Where (x,y) represents the coordinates of the preimage (the original figure) and (-y,x) represents the coordinates of the image.

Using the rule with the point (-5,7) you get the image: (-7, -5).

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
