Use the image below to answer the following question. find the value of sin x° and cos y°. what relationship do the ratios of sin x° and cos y° share?
opposite side is 8
hypotenuse has no length
adjacent is is 6.

answer:

3/5

step-by-step explanation:

use pythagorean theorem to find the hypotenuse.

c² = a² + b²

c² = 6² + 8²

c² = 36 + 64

c² = 100

c = 10

now use soh cah toa to find sin x and cos y.

sine = opposite / hypotenuse

sin x = 6 / 10

sin x = 3 / 5

cosine = adjacent / hypotenuse

cos y = 6 / 10

cos y = 3 / 5

sin x and cos y are equal.

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
