What is a Trigonometry Table? A trigonometry table is a chart listing the values of six primary trigonometric ratios for standard angles 0°, 30°, 45°, 60°, and 90°. These ratios are: It is a quick reference tool used in mathematics, physics, engineering, and real-life applications. Students use it to solve triangle, height-distance, and angle-related problems
Answer:Ozone is a molecule composed of three oxygen atoms (O₃). It is found mainly in the stratosphere, where it forms the ozone layer that protects living organisms from harmful ultraviolet (UV) radiation. In the troposphere, however, ozone acts as a pollutant and contributes to smog formation. Ozone depletion allows more UV rays to reach Earth,
