Answer:

Step-by-step explanation:

If two triangles are similar, the ratio of the area of the triangles is proportional to the squares of its corresponding sides.

area of ΔJKL/area of ΔLMN = (JK)²/(NM)²

$\frac{392}{8}=\frac{(35)^{2}}{(NM)^{2}}\\\\49=\frac{(35)^{2}}{(NM)^{2}}\\$

Cross multiply,

49*(NM)²= 1225

$(NM)^{2}=\frac{1225}{49}\\\\(NM)^{2}=25\\\\NM=\sqrt{25}\\\\$

NM = 5 cm

How do you reflect plz explain??

tangare [24]

You flip it to the other side.

First take the x and flip it's sign.

(-5,-2) then chart it. That will be a reflection.

If you need more of an explanation or help, message me.

Brainliest answer would be appreciated.

Look at the figure.

Answer:ΔSRT and ΔTRP

Step-by-step explanation:

We are given that R is a point on hypotenuse SP such that the segment RT is perpendicular to PS, therefore, PR=RS as the perpendicular bisector divides the line segment in two equal halves.

Now,

In ΔSRT and ΔTRP,

PR=SR( Since RT is perpendicular bisector, it divides PS in two equal halves)

∠PRT=∠SRT=90° (RT is perpendicular bisector of PS)

RT=RT(Common)

Therefore, by SAS rule of congruency,

ΔSRT ≅ΔTRP

Hence, Option D is correct.

What is the total volume of all four lockers if one side of a locker is 2 feet long?

Anon25 [30]

Answer:

32ft³

Step-by-step explanation:

Let the shape of the locker be cubic in nature.

Volume of a cube = L³

L is the side length of one of the lockers

Volume of four lockers = 4L³

If one side of the locker is 2feet long, then L = 2ft

Substitute into the formula;

Volume of four lockers = 4(2)³

Volume of four lockers = 4(8)

Volume of four lockers = 32ft³

Hence the total volume of all four lockers is 32ft³
