Answer 8

@ribhu

Answer 9

\(AC^2 + BC^2 = AB^2\)

Plug in what we know:

\(5^2 + 12^2 = AB^2\)

Solve for 'AB', tell me what you get.

Answer 10

13?

Answer 11

Yep, you got it.

Answer 12

Now we can set up a proportion.

\(\dfrac{AC}{AB} = \dfrac{AB}{AD}\)

Plu gin what we know:

\(\dfrac{5}{13} = \dfrac{13}{AD}\)

Cross multiply and solve for 'AD'.

Answer 13

Can you do that? @callmechris99

Answer 14

hmmm let me try real quick

Answer 15

is 65 the answer

Answer 16

No..

Cross multiplying gives us:

5 * AD = 13 * 13

5AD = 169

Divide 5 to both sides, what's 169 / 5?

Answer 17

i did that

Answer 18

Yes, but 65 is still incorrect. Tell me what you get when you divide 169 / 5.

Answer 19

which is 33.8

Answer 20

hahah

Answer 21

Yep, you got it.

Answer 22

\(AD = AC + CD\)

Plug in what we know:

\(33.8 = 5 + CD\)

Subtract 5 to both sides what's 33.8 - 5?

Answer 23

6.75

Answer 24

Um, no check again.

Answer 25

28.5

Answer 26

28.8***

Answer 27

Yep, that's our answer.
