    Use the \(Soh Cah Toa\) rule to help you. You are given an angle and the side opposite the angle, can you figure out how to work out the rest?

    Soh Cah Toa..means: Sin=Opposite/Hypotenuse Cos=Adjacent/Hypotenuse Tan=Opposite/Adjacent

    You have the angle and the length of the side opposite the angle. So you can work out either the adjacent side or the hypotenuse using \(SohCahToa\). Say we want to find QS. This forms the hypotenuse, and we have the opposite side (QR), so we use \(sin (\theta)= QR/QS\). I.e. \(sin(30)=7/QS \therefore QS = 7/sin(30) \)

    By 'Opposite', 'Adjacent'..we mean the sides that are opposite or adjacent to the angle..

    A) RS = 14, QS = 7 2 B) RS = 14, QS = 7 3 C) RS = 7 3 , QS = 14 D) RS = 7 2 , QS = 14
