Keep in mind that sin(angle) = opposite/hypotenuse

jimthompson5910 (jim_thompson5910):

So what is sin(theta) ?

OpenStudy (anonymous):

im not sure @jim_thompson5910

jimthompson5910 (jim_thompson5910):

which side is completely opposite of theta

OpenStudy (anonymous):

5? so C

jimthompson5910 (jim_thompson5910):

5 is the adjacent side

jimthompson5910 (jim_thompson5910):

since it's right next to theta

jimthompson5910 (jim_thompson5910):

|dw:1404435960669:dw|

OpenStudy (anonymous):

ok? so the answer is 5? @jim_thompson5910

jimthompson5910 (jim_thompson5910):

sin(theta) = opposite/hypotenuse

OpenStudy (anonymous):

12/13 @jim_thompson5910

jimthompson5910 (jim_thompson5910):

correct

OpenStudy (anonymous):

thanks. can you help me with 2 more? @jim_thompson5910

jimthompson5910 (jim_thompson5910):

I'll help with one more

jimthompson5910 (jim_thompson5910):

Go ahead and ask

Find the cosine ratio of angle Θ. Hint: Use the slash symbol ( / ) to represent the fraction bar, and enter the fraction with no spaces.

jimthompson5910 (jim_thompson5910):

You would use cos(theta) = adjacent/hypotenuse
