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

We have the equation 1/2x + 200 =1200 so we know that we have 200 already as one of the numbers so 1/2 is half of x + 200 equals 1200 since we have 200 we know that 1/2 of x is going to be 1000 because 1000+200=1200 meaning x is 2000. So your answer would be x=2000 or 1/2 2000 + 200=1200
