Question

Can u explain how to do this question..pls​

Answer 1

Answer:

RS ≈ 5.39

Step-by-step explanation:

Calculate the length using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = R(- 2, 6) and (x₂, y₂ ) = S(- 4, 1)

RS = $\sqrt{(-4+2)^2+(1-6)^2}$

     = $\sqrt{(- 2)^2+(-5)^2}$

     = $\sqrt{4+25}$

      = $\sqrt{29}$

      ≈ 5.39 ( to 2 dec. places )

Answer 2

Answer:

use this formula, you will get the answer

Step-by-step explanation:

√(x2-x1)²+(y2-y1)²
