Question

Trig:
Find x so the distance between (x,2) and (1,5) is √13

Answer 1

Distance formula!!

Answer 2

How do you set it up?

Answer 3

(x-2)^2 + (2-5)^2 = Root 13

I believe that is it

Answer 4

x-1 **

Answer 5

(1-x)^2+(5-2)^2=13
1+x^2-2x+9=13
1+x^2-2x-4=0
x^2-2x-3=0
solve for x
x^2+1x-3x-3=0
x(x+1)-3(x+1)=0
(x+1)(x-3)=0
x=-1 0r 3

Answer 6

Thank you Dhashni I wasn't sure if i was supposed to put the square root on top of the 13
