Question

What is the length of AD

Answer 1

You will need this theorem:

Answer 2

would AD=13?

Answer 3

AB*AD = AE*AC

7*(7 + x) = 6*13 where x = BD. Solve for x @neardtron1

Check to make sure I entered the numbers correctly, please. Thanks.

Answer 4

>>would AD=13? I did not get that.

Answer 5

Solve this and you won't have to guess:

7*(7 + x) = 6*13 where x = BD. Solve for x @neardtron1

Answer 6

I am still confused, whenever I try to calculate it I get a weird number

Answer 7

7*(7 + x) = 6*13
49 + 7x = 78
7x = 29
x = 29/7 is approx 4.14

AD = AB + BD = 7 + 4.14 = 11.14 --> what I got.

Answer 8

Thank you! I understand now
