How do I find the value of x for a pair of congruent triangles

Andreyy89

Hi there!

For congruent triangles, all angle measures and sides are congruent. So, if you look at the other triangle, and find the corresponding side, it will be the same measure.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Solve this system of linear equations. Separate the x- and y-values with a comma. -3x=42-16y 14x=76-16y

myrzilka [38]

Answer:

$(2,3)$

Step-by-step explanation:

The given equations are:

1st: -3x=42-16y

2nd: 14x=76-16y

Subtract the first equation from the second one:

14x--3x=76-42-16y--16y

14x+3x=34-16y+16y

17x=34

$x=\frac{34}{17}=2$

We plug in x-value into the second equation to get:

14(2)=76-16y

14x=76-32

28-76=-16y

-48=-16y

Divide both sides by -16

y=3
