This week in math I learned how to find an angle in a right angle triangle using trigonometry. When finding an angle, you need to first label the triangle with the hypotenuse, opposite, and adjacent sides. you then use the two sides that have a measurement and find which sign you need using Soh Cah Toa. For example, if the sign you are using is Cosine, then your formula would be Cos times x equals Adjacent divided by Hypotenuse. You then need to get the “x” by itself using a reverse sign button on your calculator which is the sign to the power of negative one. Your equation would be x equals cosine to the power of negative one times (adjacent divided by hypotenuse).
