Question

if the distance between two points A(x,-4) and B(-8,2) is 10 then find A​

Answer 1

Hey mate
Here is your answer :--

Given coordinates of points are A(x,-4)

B(-8,2)

here x1 = x. x2 = -8 y1 = -4 y2 = 2

by distance formula :-

√ (x2- x1)² + (y2- y1)²
10= √ (-8 - x) ² + ( 2- ( -4)²

squaring both the sides

100 = (-8-x)² + 36)

100-36 = (-8 - x) ²
64 = (-8-x)²

Taking square root on both the sides

8 = -8-x

8 + 8 = -x

-x = 16

so, x = -16

Final answer :- A(-16 , -4)

Hope this help you mate
