Can someone help me with this problem If \angle AOC∠AOCangle, A, O, C is a right angle and m \angle AOB = 79^\circm∠AOB=79

m, angle, A, O, B, equals, 79, degrees, what is m \angle BOCm∠BOCm, angle, B, O, C?

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

Is the figure congruent? yes or no?
