Question

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?

A right triangle is shown with one leg measuring 15 and another leg measuring 8. The angle across from the leg measuring 8 is marked x degrees and the angle across from the leg measuring 15 is marked y degrees.

Answer 3

Use Pythagorean theorem to determine the hypotenuse

Hypotenuse^2 = leg^2 + leg^2

Answer 4

I already have the length of the hypotenuse i just need help finding the value of each angle

Answer 5

Then cos(angle) = adjacent/hypotenuse

Sin(angle) = opposite/hypotenuse

Answer 6

ok hold on

Answer 7

so for the sin i got 8 divided by 17 which is 0.47

Answer 8

and then for the cos i got 4 divided by 17 which gave me 0.17

Answer 9

Be careful

It's asking for sin(x) and cos(y)

Answer 10

Your sin is right

Check cos again from the perspective of angle y

Answer 11

oh whoops i mean to do 8 divided by 17 which gives me 0.47

Answer 12

Good. So it's 8/17 for both

Answer 13

The "relationship" is that both are equal

Answer 14

so that would be my answer

Answer 15

Yup

Answer 16

awesome thank you!

Answer 17

could you maybe help me with one more question?

Answer 18
