-194) and D(p, 3) are the vertices of aExample 10: If the points A(6, 1), B(8.2), C(9, 4) and D(p. 3) are theparallelogram, taken in order, find the value of p. |

Answer» By using distance formula, take two points B(8,2) and D(p,3) distance formula is √(x₂-x₁)²+(y₂-y₁)² in point B 8 is x₁ and 2 is y₁ in point D p is x₂ and 3 is y₂Now, =√(p-3)²+(3-2)² =√(p-8)²+(1)² =p-8+1 =p-7 ⇒p=7 |
