Find the volue of x for which the distance between the points P( 2,_3)and Q(x,5) is 10 units

Answer»

Answer:

Step-by-step explanation:

GIVEN:

Two POINTS be A(2,-3),B(x,5)

DISTANCE between AB = 10 units

Distance formula =\sqrt{(x2-x1)^2+(y2-y1)^2}

                                 \sqrt{(x-2)^{2} +(5+3)^{2} }= 10

                                  (x-2)^{2} +8^{2} =100

                                   (x-2)^{2} = 100-64 = 36\\ (x-2) = 6\\ x=8
