Answer:
3.1 feet
Step-by-step explanation:
Use the Pythagorean Theorem to find 0.5x and then multiply it by 2 to find x.
1.4²+b²=2.1²
1.96+b²=4.41
b²=2.45
b=
b≈1.56524758
x≈1.56524758×2
≈3.13049517
≈3.1 ft

answer for number a is 3/2
answer for number b is 6
answer for number c is 8
If it bisect, then using the Line Bisector Theorem, it must be equal.
So x+6=4x-21
get like terms on 1 side
x+6=4x-21
-x. +21
27= 3x
x=9
plug the x in
CD= 9+6
CD=15
I would say around 41.3% I'm sorry if I am wrong :/
62/150 around 0.413
