In this Loom, I&apos;ll be teaching you about angles of elevation and depression and how they can be used to solve simple problems in trigonometry. We&apos;ll start by learning how to find the height of a building or mountain using a clinometer and the angle of elevation. Then, we&apos;ll dive into the formulas we need to know, such as Pythagoras theorem and the trigonometric ratios of sine, cosine, and tangent. We&apos;ll also learn how to find the area of a triangle. Throughout the video, I&apos;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&apos;ll be able to solve problems involving angles of elevation and depression like a pro!</description></oembed>
