This week I will be focusing on how to find and angle of a right triangle with only 2 side lengths given. It is quite easy to do this process as it is pretty much the same as finding a side length but just using inverse functions, such as inverse sine, inverse cosine, and inverse tangent. The formula is to find the the side lengths and what angle you want to find and you just do the inverse function and then put the fraction. This method is an easy way to find an angle while only having the length of two sides, but remember to inverse the functions or else you will get an error. Also make sure you check the angle because if it is more than 90 degrees then you know that something is wrong and make sure you do it again. Using common sense is very important.

Below I have some examples:
