Question
The length of a line segment A, B is 10 units. The
coordinates of point A are(2,3) and the value of ordinate of point B is 5. Then find the value of abscissa of point B.Solution
D = 10 unit Co-ordinates of point A = (2,3) Co-ordinates of point B = (x,5) Let the abscissa of point B is x - Length of segment A, B D = √( x₂-x₁ )² +(y₂-y₁ )² 10 = √((x-2)²+(5+3)²)squaring both side…. (10) ² = (x-2) ² + (8) ² 100 = (X-2) ² + 64 (X-2) ² = 36 X-2 = ± 6……. X = 8, X = -4
