Question

Find the length of the second leg of the triangle round to the nearest hundredth

Answer 1

`\displaystyle (3√(230))/(5)`

Step-by-step Step-by-step explanation:

Use the Pythagorean Theorem:

`\displaystyle a^2 + b^2 = c^2 \\ \\ 9,7^2 + b^2 = 13,3^2; √(82,8) = √(b^2) \\ \\ (3√(230))/(5)\:[or\:9,0994505329...] = b`

So, you have this:

`\displaystyle 9,1 ≈ b`
