Find the length of the third side. If necessary, round to the nearest tenth.914
Zina [86]

The given trinagle is a right angle triangle. let the missing side be x. To find x, we would apply the pythagorean theorem which is expressed as

hypotenuse^2 = one leg^2 + other leg^2

From the triangle,

hypotenuse = 14

one leg = 9

other leg = x

Thus, we have

\begin{gathered} 14^2=9^2+x^2 \\ 196=81+x^2 \\ x^2\text{ = 196 - 81 = 115} \\ x\text{ = }\sqrt[]{115} \\ x\text{ = 10.72} \end{gathered}

To the nearest tenth, the length of the third side is 10.7

Because these are opposite and they both have complimentary angles, you can set them equal to each other and solve for x
