Question

Pls ASAP help me with number 14

Answer 1

D. 19

Explanation:

because they are parallel bases you can compare

63/57 = 21/x

x = 19

Answer 2

Answer: D. 19

Let x by the length of CG. Since the two bases are parallel, we can create the following equation using proportions:

`(63)/(21)=(57)/(x)`

Simplify left side of equation

`3=(57)/(x)`

Multiply both sides by x

`3x=57`

Divide both sides by 3

`x=19`

Let me know if you need any clarifications, thanks!
