Find the length of leg " a" if leg "b" = 12 and the hypotenuse "c" is 13

quester [9]

A^2 + b^2 = c^2

a^2 + (12)^2 = (13)^2

a^2 + 144 = 169

a = 5

And, the total households in the market = 200,000 = Y

So, the rating for men 18-34 for program x is

$= \frac{X}{Y}$

$= \frac{15,000}{200,000}$

= 7.5 rating points
