Answer from: haylie1456

Step-by-step explanation:

L is at -3 and M is a 3, the difference between those is 6 meaning LM is 6, M is at 3 and N is at 9 meaning MN is 6. So we have 6 and 6 right now equaling 12, and LN is a total of 12 units, so 12 plus 12 equals 24

Answer from: jwoodsk7598

26 units

Step-by-step explanation:

Perimeter is the sum of the side lengths of the polygon. In this case, it's:

LM + MN + LN

We need to use the distance formula here to find LM and MN. The distance formula states that to find the distance between points and , we must use the equation:

First find LM. L has coordinates of (-3, 2) and M has coordinates (3, 5). So, the distance between the two is:

Then this simplifies to: ≈ 6.71 ≈ 7

Now, find MN. M has coordinates (3, 5) and N has coordinates (9, 2). So, the distance between the two is:

This simplifies to: ≈ 6.71 ≈ 7

Finally, LN is easily calculated because L and N are at the same y-coordinate, so we can just count how many units apart they are: 12.

Finally add these three numbers together: 7 + 7 + 12 = 26

The perimeter is thus about 26 units.

Hope this helps!

Answer from: Quest

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

$ab^2+ac^2=bc^2$

$ab^2+ac^2=x^2$ )

triangle abd and cba are similar,

$\frac{ab}{bc}=\frac{bd}{ab}$

$ab^2=bc\cdot bd$

$25=bc\cdot bd$ (2)

triangle cad and cba are similar,

$\frac{ac}{bc}=\frac{cd}{ac}$

$ac^2=bc\cdot dc$

$7\times 7=bc\cdot dc$

$49=bc\cdot dc$ )

using (1), (2) and (3), we get

$25+49=x^2$

$74=x^2$

hence proved.

therefore option 2 is correct.
