Look at the triangle ABC. What is the length of the side AB of the triangle? A.) 3 B.) 5 C.) Square root of 6 D.) Square root of 13

Step-by-step explanation:

To find the length of AB we use the formula

Where

(x1 , y1) and (x2 , y2) are the points

From the question

A is (4 , 5) B is (2 , 2)

So the length of AB is

We have the final answer as

Hope this helps you

sqrt(13) = c

Step-by-step explanation:

The length of BC = 4-2 =2

The length of AC = 5-2 =3

We can use the Pythagorean theorem

a^2 + b^2 = c^2

2^2 + 3^2 = c^2

4+9 = c^2

13 =c^2

Take the square root of each side

sqrt(13) = c

it would open into a square depending on the type of envelope i’m not sure about the second part
