HELP please!!!!
If sin y° = and tan y° = ,what is the value of cos y°?
I cant send the picture, but the triangle is a right triangle,
the right angle is on the bottom right, and the "y" angle is above it, (and the hypotenuse is the top line.)
Here are some choices too!

cos y° = 9c
cos y°= 9/d
cos y°= d/c
cos y° = 9d
