If you know that two objects are similar, you can use proportions and cross products to find the length of an unknown side. Let's find the length of side DF, labeled x. We read this proportion as: "AC is to AB as DF is to DE." Now, substitute in the lengths of the sides. Take the cross product to get the equation.Use the Pythagorean theorem to solve for the missing length. Replace the variables in the theorem with the values of the known sides. Square the measures and add them together. The length of the missing side, c, which is the hypotenuse, is 50. The triangle on the right is missing the bottom length, but you do have the length of the hypotenuse. Example: Find the value of x in the triangle shown below. 106 ∘ x ∘ 42 ∘. We can use the following equation to represent the triangle: x ∘ + 42 ∘ + 106 ∘ = 180 ∘. The missing angle is 180 ∘ minus the measures of the other two angles: x ∘ = 180 ∘ − 106 ∘ − 42 ∘. x = 32. The missing angle is 32 ∘ .
