The best bench mark to use is an inch. She should use an inch because centimeters are too small and the steps might be less than a foot.
<span>when the altitude is </span>drawn from the vertex of the right angle<span> of a right triangle to its hypotenuse, the altitude equals the product</span> of the two segments of the hypotenuse<span>.
(w+9)</span>²=8*18=144
w+9=12 or w+9=-12
w=3 (discard the negative number)
use the same method, z=√(9*11)=3√11
next, you can use the Pythagorean theorem to find x and y.
x=√(9²+99)=√180=6√5
y=√(11²+99)=√220=2√55
Is it clockwise rotation or counterclock wise?
If it’s clockwise rotation then C is the answer but if it’s counter lock wise rotation then the answer is A.
