a radio wave had a frequency of 600,000 Hz and travels at a speed of 300,000,000 m/s. what is the wavelength of the radio wave

the one below it is a function

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

1/4 is the asnwer cuz 5/20 is the faction
