Answer:

The answer to your question is below

Explanation:

Data

1) AB = 6 BC = 4 AE = 9 ED = ?

Use proportions to solve this problem

AB / AE = 6/9 (AB + BC) / (AE + ED) = (6 + 4) / (9 + ED)

-Equal both proportions

6/9 = 10 / (9 + ED)

-Solve for ED

9 + ED = 10(9)/ 6

-Simplification

9 + ED = 90/6

9 + ED = 15

ED = 15 - 9

-Result

ED = 6

2.- AB = 12 AC = 16 ED = 5 AE = ?

Use proportions to solve this problem

AE / AB = AE / 12 AD/AC = (AE + 5) / 16

-Equal both proportions

AE/12 = (AE + 5 ) / 16

-Solve for AE

16AE = 12(AE + 5)

16AE = 12AE + 60

16AE -12AE = 60

4AE = 60

AE = 60/4

-Result

AE = 15
