(35 points!) What is the length, in units, of segment CD? 5.50 12.25 8 14

Using Pythagorean’s Theorem

7^2 - 4^2 = 33

Root 33 = length BC

Now since it appears that they are similar triangles - by their shapes.

Relate root 33 to 7

7/ root 33 = 1.22~

1.22 • 7 = length DC since it relates the length of hypotenuse of first triangle to second triangle.

Therefore length is roughly 8.54~
