Question

the distance between the two points (8,x)&(x,8) is 8 then find x​

Answer 1

Step-by-step explanation:

Use distance formula between 2 points

Root(x2-x1)square + (y2-y1)Square

So

Root (8-x)Square +(x-8)Square

Now square both side

(8-x)Square + (x-8) = 64

64 +xsquare - 16x +xsquare + 64 - 16x = 64

2xsquare - 32x +64 =0

X Square - 16x - 32 = 0

Now solve it by quadratic formula

Answer 2

Answer:

when we solve this then we get a equ-x^2+128-32x=0

from the value of x will be( 32+✓768)/2and other will be. (32-✓768)/2
