Question

HELP!
CD is the perpendicular bisector of AD.
Find AC AD and AE
ill have pic below

Answer 1

Pythagorean theorem:

a^2 + b^2 = c^2 where a, b are regular sides and c is the hypotenuse. You have all the info you need.

Answer 2

alright alright tahtnk you

Answer 3

@saifoo.khan think you could help me out :)

Answer 4

How far did you get? Show me your work and we can do this together.

Answer 5

im kinda confused about that with all the x's and y's so do I have to solve for them first befor I can do anything?

Answer 6

You do not have to solve for x and y. You can figure out the problem as a system of equations.

Answer 7

Ok so the do I take9y-6^2+3x=c^2

Answer 8

to find AC and AD

Answer 9

(9y-6)^2 + (3x)^2 = c^2.

81y2 - 108y + 36 + 9x^2 = c^2

Then you basically take the square root of that, which I can't factor. Is there a way to find x or y? Do you have a numerical reference?

Answer 10

I see you have 5x = 6y up there, is that a typo?

Answer 11

yes it supposta be 5x+6y

Answer 12

so the answers I get for lthe problems you did will be AC AD?

Answer 13

well it depends what format you need them in. if your teacher wants polynomials give him polynomials.

Answer 14

so I got 81y-36+9=c^2 and 6561y-11664y+36+81......I don't have a teacher im homeschooled and this is all the book gives me to solve
