HELP WILL MEDAL!!!!! Look at the figure. If tan x° =z/10 and cos x° =10/y , what is the value of sin x°? (1 point)

OpenStudy (anonymous):

sin x° = z/y sin x° = y/z sin x° = 10z sin x° = 10y

I'm sorry, I've hardly learned this yet. I wish I could help you, but as I can't maybe @tkhunny or @mathmale or @pooja195 could assist you. I'm really really sorry again! :/

Looks as though you've left out some key info: numerical values. If need be, draw your trig expressions in the Draw utility, below.

OpenStudy (mathmale):

tan x = ? cos x = ?

this is everything

All right. my mistake; you did share everything about this problem. Copy down the given diagram (pic of a triangle). Note that this is a right triangle, because it has 1 - 90-degree angle. One angle is labeled x. Label the side opposite angle x with "opp" (meaning opposite side).

OpenStudy (mathmale):

Label the hypotenuse "hyp". Label the remaining side "adj" (for "adjacent side."

OpenStudy (mathmale):

Are you able to do that, perhaps using the Draw utility?
