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? @jim_thompson5910

jimthompson5910 (jim_thompson5910):

The image is missing.

OpenStudy (anonymous):

im trying to post it

OpenStudy (anonymous):

its not letting mme ill draw it

jimthompson5910 (jim_thompson5910):

let's make z the length of the hypotenuse |dw:1413936273311:dw|

jimthompson5910 (jim_thompson5910):

what is sin(x) equal to?

OpenStudy (anonymous):

what do you mean? im sorry im new to this and im horrible at math lol @jim_thompson5910

jimthompson5910 (jim_thompson5910):

ok, in general, what is sine equal to? it's a ratio of ____ to _____

jimthompson5910 (jim_thompson5910):

sine of the angle I meant

jimthompson5910 (jim_thompson5910):

it involves the adjacent, opposite, hypotenuse (well 2 of those 3)

OpenStudy (aum):

For the angle 'x' there is an opposite side, an adjacent side and a hypotenuse. sin(x) = ?

OpenStudy (anonymous):

ohhhhhhhhhhh

OpenStudy (anonymous):

opp/hypotenuse

jimthompson5910 (jim_thompson5910):

correct, so in this drawing |dw:1413936608916:dw| sin(x) = ???

OpenStudy (anonymous):

so z is hypotenuse

OpenStudy (anonymous):

15 is opposite?

jimthompson5910 (jim_thompson5910):

focus on angle x

OpenStudy (anonymous):

what would 15 even be??

jimthompson5910 (jim_thompson5910):

15 is the adjacent for angle x

jimthompson5910 (jim_thompson5910):

notice how it's the closest leg to angle x

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

so it would be 8 for the opposite?

jimthompson5910 (jim_thompson5910):

correct

jimthompson5910 (jim_thompson5910):
