Answer :
- (x₁ , y₁) = (-2 , 5)
- (x₂ , y₂) = (x , -7)
Distance between both points = 13
We have to find value of x
Distance between two points can be measured by using this formula :
- d = √[(x₂ - x₁)² + (y₂ - y₁)²]
⭆ 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
Hope It Helps!
