Question

Find the length of the missing sides in the triangle

Answer 1

b.
`\displaystyle x ≈ 9,9, y = 7`

Explanation:

In a 45°-45°-90° triangle, both legs are congruent
`\displaystyle [x],`whereas the hypotenuse is represented by
`\displaystyle x√(2).` So, evaluate:

`\displaystyle hypotenuse \hookleftarrow x√(2) \\ \\ 9,8994949366... = \boxed{7√(2)}`

Therefore, you have this:

`\displaystyle 9,9 ≈ x`
