Use the image below to answer the following question. What relationship do the ratios of sin x° and cos y° share? The ratios are opposites (-6/8 and 6/8). The ratios are reciprocals (6/8 and 8/6). The ratios are both negative (-6/10 and -6/10). The ratios are both identical (6/10 and 6/10).

I got sin x° = 6/10 and cos y° = 8/10

Clearly I did something wrong

x and y are complementary angles. that means that their cofunctions are the same.
what is the sin(x) = ?
OpenStudy (anonymous):
6/10
OpenStudy (anonymous):
great! what is the cos(y) = ?
OpenStudy (anonymous):
8/10
OpenStudy (anonymous):
nope... check again

ooooooh. It's 6/10
OpenStudy (anonymous):
that's right! godd job!
OpenStudy (anonymous):
good
OpenStudy (anonymous):
But I thought cos was Adjacent/Hypotenuse
OpenStudy (anonymous):
it is. but you have to be looking at the appropriate angle.
for cos(y), we have to look at what side is adjacent to the angle y.
