Question

please explain HOW to work this out...

Answer 1

Answer:

$\sqrt{68}$

Step-by-step explanation:

Well u can use this formula

$\sqrt{(x_2-x_1)^2 + (y_2 - y_1)^2}$

TN = $\sqrt{68}$

Answer 2

Answer:

Step-by-step explanation:

For solving this Question, you need to know the distance formula, which is used for finding the distance between two given points in a Plane...

Distance Formula=$\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }$

Let T, 1 be x1 and 5 be y1

and N, 3 be x2 and -3 be y2

Then, TN=$\sqrt{(3-1)^{2}+(-3-5)^{2} }\\\sqrt{(2)^{2} +(-8)^{2} }\\ \sqrt{4+64}\\\sqrt{68}$

Thus, TN=$\sqrt{68}$ units....
