In a triangle, if the angle is 45 degrees and the adjacent side is 5√2, what is the length of the opposite side? A. 5 B. 5√2 C. 5√3 D. 10 相关知识点: 试题来源: 解析 B。因为是 45 度角,所以正切值为 1,即对边/相邻边 = 1,所以对边 = 相邻边 = 5√2。
1+45°=90° [Substitute] ∠1 = 45° [Subtract] From equation (1) – ∠5 = 45° Hence, ∠1 and ∠5 are corresponding angles, and their measure is 45°. Frequently Asked Questions on Corresponding Angles What are alternate angles? What is a right angle? Are all corresponding angles eq...

When two straight lines or rays meet at a common endpoint, an angle is formed. The common point of contact of the two rays is called the vertex of an angle. We use the symbol ∠ to represent an angle. We use degrees (°) to measure an angle using a protractor. For example, 45 de...
