Question

What is the length of segment BC 4 5 6 7

Answer 1

Answer:

Length BC : 5 units.

Step-by-step explanation:

Given  : Line BC with B (  -3 ,-2) and C ( 0 ,2) .

To find : What is the length of segment BC.

Solution : We have given  Line BC with B (  -3 ,-2) and C ( 0 ,2) .

Length of BC  mean distance between the point B and C.

Distance formula  : $\sqrt{(x_{2} -x_{1})^{2} +(y_{2} - y_{1})^{2}}$.

$x_{1} = -3\\x_{2} = 0\\y_{1} = -2\\y_{2} = 2$.

Plug the values in above formula.

Length BC : $\sqrt{(0 -(-3))^{2} +(2 - (-2))^{2}}$.

Length BC : $\sqrt{(0+3))^{2} +(2 +2))^{2}}$.

Length BC : $\sqrt{(3)^{2} +(4)^{2}}$.

Length BC : $\sqrt{9 +16}$.

Length BC : $\sqrt{25}$.

Length BC : 5 units.

Therefore, Length BC : 5 units.

Answer 2

The correct answer is 5 because the square root of 25 is 5

Hope this helped :)
