Solve this for the brainlist

Answer 1

Answer:

22.4

Step-by-step explanation:

using altitude theorem, the height of the triangle is 20

let y = height

10/y = y/40

y² = 400

y = $\sqrt{400}$ or 20

Now we can us the Pythagorean Theorem to find 'x':

10² + 20² = x²

100 + 400 = x²

x=$\sqrt{500}$ ≈ 22.4
