OpenStudy (anonymous):

does it tell you what the whole triangle equals?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

|dw:1379458991299:dw|

OpenStudy (anonymous):

if im not mistaken, i believe that you add the sides AB and AC together, and subtract it from either 90 or 180, but im pretty sure you subtract it from 90. So i think the answer would be 71.

hartnn (hartnn):

well, not actually are you introduced to trigonometry ? sin, cos and tan functions ?

OpenStudy (anonymous):

THATS WHAT im in but i dont really understand it

hartnn (hartnn):

cool, so can you identify adjacent side and opposite side of an angle ?

hartnn (hartnn):

BC is the hypotenuse, because its opposite the right angle! |dw:1379459861999:dw| ok?
