Math Help!!

Given A(1,-2) and B(3,5), C is located such that the y-coordinate of B is greater than that of either A or C. If the angle of B in the triangle ABC is a right angle and AC = sqrt(2809)/7, what is the x-coordinate of C?

I NEED TO ANSWER THIS BEFORE SUNDAY!!

Thanks,

tries to think...

-A

Hmm. What class is this? lol

just get graph paper put points A and B on then get a ruler put B on the corner have on side hitting A then draw the line 90 degrees from A going to the right

i don't know what the sqrt(2809) /7 means tho
i'm assumeing you mean the length of the line AC in which you have to use trial and error to see how far away C is
