Figure a is the preimage. which figure is the image of figure a after a dilation with a scale factor of 2 and a center of (0, 0)? a. figure r b. figure s c. figure t d. figure u

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
