Question

Look at the figure below: an image of a right triangle is shown with an angle labeled y degrees If sin y° = s divided by 8 and tan y° = s divided by t, what is the value of cos y°?

cos y° = 8s
cos y° = 8t
cos y°= t / 8
cos y°=8 / t

Answer 1

the answer is :

cos y°= t / 8

Explanation:

I promise! I got this right, and.....you are welcome.

Answer 2

Cos y = t / 8

Explanation:

Using the hints given in the question, the omitted tribagke will look like the triangle attached on the picture ;

From trigonometry :

Sin y = opposite / hypotenus

Sin y = s / 8

Opposite side = s ; hypotenus = 8

Tan y = opposite / Adjacent

Tan y = s / t

Adjacent side = t

Then ;

Cos y = Adjacent / hypotenus

Hence,

Cos y = t / 8
