Using the 12 cm side and the given angle, can you find the height using trig?
OpenStudy (anonymous):
Do I have to use the pythagorean theorem?
OpenStudy (mathstudent55):
You can't since you have only one side given. You need to use trig.
OpenStudy (anonymous):
Okay, so how can I do that?

For the given angle of 73 deg, is h the adjacent or the opposite leg?
OpenStudy (mathstudent55):
12 cm is obviously the hypotenuse.
OpenStudy (anonymous):
Yeah.
OpenStudy (mathstudent55):
Right, opp/hyp.
Which trig function is opp/hyp?
OpenStudy (anonymous):
I get the two legs mixed up.
