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

Answer: -6. 4. -3,75. 37.

Step-by-step explanation: -20|+10-2²= -6, since a minus×minus give you a + therefore -2²=4.

2³+(-8)= 12-8=4, a minus×plus gives you a minus.

-2,50+(-1,25)=-2,50-1,25=-3,75. |-10|+|20|-5²-(-2)=-10+20+25+2=37.
