You can put this solution on YOUR website! if i have a right triangle with side lengths 12 and 6, what would the degree's on the inside be? (this is using sine, consine, and tangent laws)
Since the triangle is a right triangle the third side is the hypotenuse H and has the value sqrt(12^2 + 6^2) = sqrt(180) = 6*sqrt(5)
You can then calculate the sine (i.e. side opposite divided by hypotenuse) of the angle opposite side 6 as 6/(6*sqrt(5), the cosine of the angle opposite side 6 (that is, adjacent to side 12) as 12/(6*sqrt(5) etc.
Similarly you can find the corresponding trig values for the other angles.
