In a class of 28 students, 19 have a cat and 6 have a dog. There are 5 students who do not have a cat or a dog. What is the probability that a student who has a cat also has a
dog?

where is the picture

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
