Question

Calculate the value of cos O in the following triangle.

Answer 1

could u find the hypotenuse, using pythagoras theorem ?

Answer 2

Mmm yeah I could, but then there's that whole thing with the cos = adjacent/hypotenuse aannddd then I get lost.

Answer 3

so what u got hypotenuse as ?

Answer 4

544, just have no idea which one the adjacent side is. (stupid question, sorry!)

Answer 5

actually good question,

the side exactly opposite to angle theta is opposite side, then you know which is hypotenuse, the remaining side is adjacent side.
