In this Loom, I'll be teaching you about angles of elevation and depression and how they can be used to solve simple problems in trigonometry. We'll start by learning how to find the height of a building or mountain using a clinometer and the angle of elevation. Then, we'll dive into the formulas we need to know, such as Pythagoras theorem and the trigonometric ratios of sine, cosine, and tangent. We'll also learn how to find the area of a triangle. Throughout the video, I'll be giving you practice problems to solve, so make sure to have a pen and paper handy. By the end of this video, you'll be able to solve problems involving angles of elevation and depression like a pro!"}
