Question

Charlotte is creating a triangular pennant with geometry software.

Answer 1

Answer:

Base of the Pennant = 330 pixels

Scale Factor =0.6

Step-by-step explanation:

The base measure of the pennant on screen is 550 pixels.

The height  is 275 pixels.

$A spect Ratio=\dfrac{Base}{Height}=\dfrac{550}{275} =2:1$

If Charlotte resizes the pennant, keeping the aspect ratio  constant.

Height = 165 pixels

Therefore:

$\dfrac{Base}{165}=\dfrac{2}{1} \\\\ Base= 2 *165 =330$

Therefore, the scale factor of the dilation  $=\dfrac{330}{550}= \dfrac{165}{275}=0.6$

Base of the Pennant = 330 pixels

Scale Factor =0.6
