Look at the figure below:

An image of a right triangle is shown with an angle labeled y.

If sin y° = a divided by 6 and tan y° = a divided by b, what is the value of cos y°? (6 points)

Step-by-step explanation:

since I don't see a figure here, I have to use only the written information.

we need to remember :

tan(angle) = sin(angle) / cos(angle)

so, we have here

a/b = a/6 / cos(y) = a/(6×cos(y))

a×6×cos(y) = a×b

cos(y) = a×b / (a×6) = b/6
