Question

I need to find the angles of a right triangle with only 2 side lengths: 4 and 5.6 How would I find the angles?

Answer 1

Trigonemtry would help you with this. Sin(theta) = opposite side/hypotenuse, Cos(theta) = adjacent side/hypotenuse and tan(theta) = opposite/adjacent. You can use the inverse functions (equivalent to dividing across by the function) to find the angles. Say you had the opposite and the adjacent, you would say theta = tan^(-1) opposite/adjacent

Answer 2

So I would need to divide my opposite and adjacent then multiply by cotangent?

Answer 3

You would take the cotangent of the opposite divided by the adjacent. You can't multiply by cotangent as it is not a number in itself

Answer 4

In this case, my triangle is a 45 45 90, and it is opposite over hypotenuse, would I do Sin or cosine?

Answer 5

SOH CAH TOA, Sin involves Opposite and Hypotenuse, Cosine involves Adjacent and Hypotenuse, and Tangent involves Opposite and Adjacent.
