Using the sine function to find the missing length of the hypotenuse

Follow
Brian McLogan

Learn how to find a missing side length of a right triangle. A right triangle is a triangle that has 90 degrees as one of its angles. The trigonometric identities of right triangles give us the relationship between the angles of a right triangle and the side lengths of the right triangle. These trigonometric identities, commonly called SOHCAHTOA, are: sin x = opposite / hypothenuse; cos x = adjacent / hypothenuse and tan x = opposite / adjacent. These identities enable us to find a missing side length of a right triangle given one of the side lengths and one of the other angles of the right triangle.
