It is convenient to remember that 5-12-13 is a Pythagorean triple.
Her ladder is 12 ft above the ground where it rests on the house.
_____
Using the Pythagorean theorem, you are given the hypotenuse as 13 ft and one leg as 5 ft. Then the other leg is
.. √(13^2 -5^2) = √(169 -25) = √144 = 12
solve for x.
4x−5=7+4y
Add 5 to both sides.
4x−5+5=4y+7+5
4x=4y+12
Divide both sides by 4.
4x/4=4y+12/4
x=y+3

Have a nice day! :)
If u need to go from radius to diameter multiply radius times 2: d=2r
