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

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
