1. Draw a 30-60-90 triangle. Label all angle measures and side relationships. Using the side relationships from the figure, show that the following trigonometric identities hold true for the given angles:
a) tan 60* + sin 60*/cos 60*
b) sin (squr)2 (30*) + cos (squr)2 (30*) = 1

30-60-90 triangle how you find all 3 sides of that triangle here is a link! http://openstudy.com/users/masonman#/updates/554671efe4b0629c5c69ef37 after that sin cosine and tan definition $$\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }$$ (mhm sorry i have 5 mints otherwise i would love to explain it) btw if u don't get it then wait for other user to explain it better than me ofc!! -)
