Answer:
Step-by-step explanation:
These "special" right triangles have side length ratios that it is useful to remember.
<u>45°-45°-90° triangle</u>
Sides have the ratios 1 : 1 : √2. That is, x is √2 times as long as the side length shown as 18.
x = 18√2
<u>30°-60°-90° triangle</u>
Shortest to longest, sides have the ratios ...
1 : √3 : 2
That is, y is √3 times the length of the side marked 18, and z is 2 times the length of the side marked 18.
y = 18√3
z = 2·18 = 36
((X1+x2)/2,(y1+y2)/2)
---> ((2+2)/2,(1+4)/2)
---> (2,2.5)

Jane walked a quarter of the distance she walked on Monday, so that means she walked 4 times less hoped this helped. :]
