Quadrilateral JKLM has coordinates J(1, 2), K (4,3), L(6, 1), and M(3, 1). Determine the coordinates of the vertices of the image after a 270° rotation about the origin?

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

5+2x=a
