Given DEFGH ≅ QRSTU .
blsea [12.9K]
Using our congruency statement <span>DEFGH ≅ QRSTU, we can see which angles map onto each other. 

</span>D ≅ Q
E ≅ R
F ≅ S
G ≅ T
H ≅ U

We see that E ≅ R, and since E is 143 degrees, R = 143 degrees.

Why is this true, you may ask? When dealing with congruency, the given points/letters (they are really both) are congruent to the corresponding shapes letter/point. For example, if triangle ABC ≅ DEF, A would correspond to D, B would correspond to E, etc. When you see these types of problems, congruency will be applied to angles (it could apply to lines in other cases).

If you have any questions, feel free to ask!

Each 7th grader brings $5 for charity, while each 8th grader brings in $8. The total collected is $1380. There are 10 more 8th g
Scilla [17]

Answer:

7th graders- 100 students

8th graders- 110 students

Step-by-step explanation:

Let the number of 8th graders be represented by x and 7th graders be represented by y

<u>Equation based on number</u>

There difference between 8th and 7th graders is 10 hence equation becomes

x-y=10

<u>Equation based on contribution</u>

While x contribute each $8 and y contribute each $5, the total contribution is $1380 hence the equation becomes

8x+5y=1380

<u>Combining equations</u>

Having the two simultaneous equations which are

x-y=10

8x+5y=1380

Solving the equations.

5x-5y=50

8x+5y=1380

------------------

13x=1430

x=1430/13=110

Therefore, 8th graders are 110. Since the 8th graders were 10 more than 7th graders, the 7th graders will be 110-10=100 students
