In geometry, if you’re given a right triangle with missing angles or sides, you can use trigonometric ratios—sine, cosine, or tangent—to find them. To help you decide which of the three trigonometric ratios to use, you can label the sides of the triangle as adjacent or opposite. Explanation:. We can solve for the length of the chord by drawing a line the bisects the angle and the chord, shown below as. In this circle, we can see the triangle has a hypotenuse equal to the radius of the circle (), an angle equal to half the angle made by the chord, and a side that is half the length of the chord. By using the sine function, we can solve for.
