Trigonometry is very helpful for measuring heights and distances, especially using right triangles. In Year 9 Math, students learn how to use basic trigonometric ratios like sine, cosine, and tangent to solve real problems.
Finding Heights: Let’s say you want to find out how tall a tree is. If you stand 30 meters away from the tree and look up at an angle of 40 degrees, you can find the height using the tangent function:
Measuring Distances: If you’re standing 50 meters away from a building and look up at an angle of 60 degrees, you can calculate the height of the building like this:
By using these trigonometric ideas, we can easily measure things that might seem complicated at first. This is useful in many areas of life and different jobs!
