Charlotte is creating a triangular pennant with geometry software. The base measure of the pennant on screen is 550 pixels. The height is 275 pixels. Charlotte resizes the pennant, keeping the aspect ratio constant, so the height is 165 pixels. What is the scale factor of the dilation? What is the base of the pennant?

    Base-330 pixels

    Scale factor - 3/5

    Step by step explanation:

    It's a ratios for the base

    275/550 = 165/x

    275/550=.5

    Solving for x would mean you divide 165/.5 and get 330

    For the scale factor

    275 (x) = 165 where x is the scale factor and you solve for x by divinding 165/275
