 In this video, we will provide the solution to question number two for practice exam number one for math 12 10 In which case we're asked to compute cotangent of theta for the illustrated right triangle will go to the side here So we see our angle theta is right here And so this is going to be a basic so katoa type argument notice that with cotangent Cotangent is the reciprocal of tangent. So if I can calculate tangent, then I can calculate cotangent right here, which remember tangent is opposite over adjacent. So it's reciprocal is going to be adjacent over Opposite side. So we're looking at the adjacent side, which would be four right here The opposite side would be three. So we're going to grab a four-thirds which gives us option C
