Question

Find the length of GH!

Answer 1

Answer:

A

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = G(6, 5) and (x₂, y₂ ) = H(8, 9)

GH = $\sqrt{(8-6)^2+(9-5)^2}$

      = $\sqrt{2^2+4^2}$

      = $\sqrt{4+16}$

      = $\sqrt{20}$ ≈ 4.5 → A

Answer 2

Distance formula is square root of (x2-x1)^2 plus (y2-y1)^2
Which is the square root (6-8)^2 plus (5-9)^2
Which is 4.47
Which is approximately 4.5 hope this helps ;)
