$\bf x=rcos(\theta )\implies \cfrac{x}{cos(\theta )}=r\\\\
y=rsin(\theta )\implies \cfrac{y}{sin(\theta )}=r
\\\\
-------------------------------\\\\
r=3cos(\theta )\implies \cfrac{x}{cos(\theta )}=3cos(\theta )\implies x=3cos(\theta )cos(\theta )
\\\\\\
\boxed{x=3cos^2(\theta )}
\\\\\\
r=3cos(\theta )\implies \cfrac{y}{sin(\theta )}=3cos(\theta )\implies \boxed{y=3cos(\theta )sin(\theta )}$

Determining the Scale Factor of a Dilation Consider the dilation of pentagon ABCDE by a scale factor of If AB = 12, then A'B' A&

barxatty [35]

<h3>Answer:</h3>

If AB = 12units, then

A'B' = 1/2 × 12 = 6units.

If C'D' = 5units, then

CD = 2 × 5 = 10units.

A. 23.3 cm B. 16 cm C. 8 cm

Hitman42 [59]

B. 16 cm

Square both 20 and 12

20x20=400

12x12=144

400-144=256

find the square root of 256
and the square root is 16

so b is 16 cm
