<u>Answer</u>


= 14.6 feet


<u>Explanation</u>

The length of the ladder is 15 feet and it is place against the wall 3.5 feet from the base of the wall.

This makes a right triangle with a base length of 3.5 feet and a hypotenuse of 15 feet.

So, we can use the pythagorean theorem to calculate the height required.

a² = c² - b²

Where a and b are the legs of the right triangle and c is the hypotenuse.

a² = c² - b²

h² = 15² - 3.5²

h² = 225 -12.25

= 212.75


h = √212.75

= 14.58595215

In trapezoid RTUW, V is the midpoint of segment UW, and S is the midpoint of segment RT. Find UT.
andrezito [222]
The line VS is middle line of that trapezoid, so you know that it is

VS= (WR+UT)/2

so we will get that it is: 

<span>40= (x^2+2 +2x^2+3)/2
x = 5

Therefore, 

x^2 + 2 
5^2 + 2
