Distance between both points = 13
We have to find value of x[tex].[/tex]
Distance between two points can be measured by using this formula :
⭆ d = √[(x₂ - x₁)² + (y₂ - y₁)²]
⭆ 13 = √[(x - (-2))² + (-7 - 5)²]
⭆ 13² = (x + 2)² + (-12)²
⭆ 169 = (x + 2)² + 144
⭆ (x + 2)² = 169 - 144
⭆ (x + 2)² = 25
⭆ x + 2 = 5
⭆ x = 5 - 2
⭆ x = 3
