Ah, this my friend, is actually easier than it looks. I promise. Sort of. XD

Alright, so let's start with the basics. You have two shapes that look congruent, and obviously ARE congruent, but how they are congruent can be different.
HIJ (Shape 1) is congruently equal to (~=) shape LKJ (The order does indeed matter) by what?

Well, in terms of congruency, you have about 8 different ways, I only remember 4.
SSS (Side, Side, Side)
SAS (Side, Angle, Side)
ASA (Angle, Side, Side)
AAA (Angle, Angle, Angle)

This means that whichever it is, each must be identified as congruent to the other. If it's SAS, you must know, for certain (not you personally, you can guess, but that's not what they want, they want you to know based on the info they give you) that there are 2 sides that are congruent, and 1 angle that are congruent. Same for all the others, just plug and play. 

In the text, this question mentions that side HJ is congruently equal to JL. This means you have 1 set of sides identified as congruent. 
The text ALSO mentions that angle H is also congruently equal to angle L. This means you now have 1 set of angles that are congruently equal.

So far, you know you have 1 congruent set of sides (S) and One congruent set of angles (A)

Now, you also can see that based on what we already know, HIJ extends to LKJ, meaning the other angle would ALSO be congruent. 
This leaves you with "ASA" (Angle, Side, Angle), meaning 2 sets of angles are congruent, and 1 set of sides.

Your answer is A

~Hope this helps!

The coach of the track and field team is putting together groups of runners to run relays. Each group will need to run a race th
andrew11 [14]

Answer:

16 runner

Step-by-step explanation:

It is given that,

Each group will need to run a race that is 1/2 of a mile long. Each runner has to run 1/8 of a mile in the race.

Let there are x no of runners. ATQ,

\dfrac{1}{8}x=\dfrac{1}{2}\\\\x=\dfrac{(1/2)}{(1/8)}\\\\x=16

So, there are 16 runner that are needed for each relay race group.

On a buying trip in los​ angeles, rosaria perez ordered 120 pieces of​ jewelry: a number of bracelets at ​$77 each and a number
Digiron [165]

Let, the number of bracelets be x and the number of necklaces be y.

Given, there are 120 pieces of jewellery which are bracelets and necklaces.

So we can write the equation, x+y = 120....equation 1

Now given the price of bracelet = $7

So, the price of x bracelets = $ (7)(x) =$ (7x)

Given, the price of necklace = $13.

So, the price of y necklaces = $ (13)(y) = $ (13y)

The total amount for the jewellery given = $ 1080.

We can write the equation as,

7x + 13y = 1080....equation 2

Now from equation 1, we can write,

x = 120-y

By substituting this value of x in equation 2, we will get,

7(120-y) + 13y = 1080

840-7y+13y = 1080

840+6y = 1080

Now we will move 840 to the right side by subtracting it from both sides. We will get,

840+6y-840 = 1080-840

6y = 1080-840

6y = 240

We can get y by moving 6 to the other side by dividing it to both sides. We will get,

\frac{(6y)}{6} =\frac{240}{6}

y =\frac{240}{6}

y = 40

So we have got the number of necklaces = 40

Now we have, x = 120-40

x = 80

So, the number of bracelets = 80

We have got the required answer here.
