AB ≈ 9.85 units
Step-by-step explanation:
Calculate AB using the distance formula
AB =![\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }](/tpl/images/1088/4773/05e0c.png)
with (x₁, y₁ ) = A(1, 7) and (x₂, y₂ ) = B(10, 3)
AB =![\sqrt{(10-1)^2+(3-7)^2}](/tpl/images/1088/4773/7e5db.png)
=![\sqrt{9^2+(-4)^2}](/tpl/images/1088/4773/c25e5.png)
=![\sqrt{81+16}](/tpl/images/1088/4773/0a4a0.png)
=
≈ 9.85 units ( to 3 significant figures )
