∠A and \angle B∠B are complementary angles. If m\angle A=(x+28)^{\circ}∠A=(x+28) ∘ and m\angle B=(4x-8)^{\circ}∠B=(4x−8) ∘ , then find the measure of \angle A∠A.

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3
