Formula & Methodology
The tangent of an angle in a right triangle is the ratio of the length of the opposite side to the length of the adjacent side. For 15 degrees, we use the unit circle or a calculator.
Real-World Examples
Example 1
A right triangle has one angle of 15 degrees. The adjacent side is 5 units. Find the opposite side.
tan(15°) = opposite / adjacent = 2.6786 (using calculator). So, opposite side = 5 * 2.6786 ≈ 13.393 units.
