Please help, I’m not sure what the answer is.
Karo-lina-s [1.5K]

Answer:

The answer is 'C'

Step-by-step explanation:

Congruent simply means "the same." When a line divides two parralel lines transversals are created. This means that there are angles on both lines that are similar. To fully understand which angles would be the same, I reccommend researching "transversals" for more information, or asking your teacher about it as it is hard to explain without a proper diagram.

What is the value is of x?<br><br> A)0<br><br> B)25<br><br> C)4<br><br> D)7
iogann1982 [59]

We know that these two angles are equal to each other (There is the "congruent" sign) so we can set them equal to each other and solve for x

3x - 17 = 25 - 3x

(3x + 3x) - 17 = 25 + (-3x + 3x)

6x + (- 17 + 17) = 25 + 17

6x/6 = 42/6

x = 7

Hope this helped!
