last week dylan listened to 5 led zeppelin songs per hour at school and he had heard 4 before school started. write an equation to show the relationship between h, the number of hours he has listened to led zeppelin, and s, the total number of sings hes heard

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

answer: 60%

explanation:

÷

= 60%

answer is  

a.

7 in. x 11 in.

hope you get this right.
