Answer:
$300 | 300 Dollars of United States
Answer:
Step-by-step explanation:
The system of equations are expressed as
2x + 17y = −3 - - - - - - - - - 1
5x + 4y = 9 - - - - - - - - - - 2
In order to eliminate y, you will need to multiply equation 1 by 4 and equation 2 by 17. This would make them to have the same value of 68y.
You might choose to eliminate x instead. To do this, you will need to multiply equation 1 by 5 and equation 2 by 2. This would make them to have the same value of 10x.
That's a Congruent Triangle question.
The first thing that we should to analize is it: What figure is EFGH? The question say for us that 
and 
, therefore, EFGH is a parallelogram because its parallel sides are congruents (equals).
Now, we should to proof that 
. The simbol "≅" means congruence, that is, means that the triangles EFH and GHF are equals.
Let's proof:
is a diagonal of the parallelogram EFGH. When we have a diagonal in a parallelogram, the opposite angles are congruents (look at the picture: the blue angles are congruent and the red angles are congruents too). Therefore, 
and 
.
Both triangle has a comum side: the diagonal . The diagonal is between two angles that we know that are congruents, Therefore, by the case ASA (Angle, Side, Angle), we proof that .
