Two similar circles are shown. The circumference of the
larger circle, with radius OB, is 3 times the circumference of
the smaller circle, with radius OA.
Radius OB measures x units. Which expression represents
the circumference of the smaller circle with radius OA?

its adding 5.5 each time

step-by-step explanation:

hey there : ) your answer would be a.

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
