Find the value of the variable that results in congruent triangles. Explain. SAS (Side, Angle, Side) or ASA (Angle, Side, Angle)
Mamont248 [21]

well, let's keep in mind that the SAS postulate, so if one Side and the Angle next to it and the following Side after the angle are equal on both triangles, both triangles are congruent.  Now, we have the angle 30° with sides and 9 and 2x and sides 9 and x + 4, well, the 9's are equal, dohh, you know, if only the 2x  = x + 4, we'd be golden

2x = x + 4\implies 2x - x = 4\implies \boxed{x = 4}

Will give u brainliest pls help me out
damaskus [11]

Answer:

Option 1

Step-by-step explanation:

First we need to analyse the question to figure out what we need to do. The question is saying that a line is parallel to the y-axis. We know that the y-axis goes up and down, meaning that our line should be pointing up and down crossing the point (2,-7). In order to find where the line is placed, we would have to look at the x-axis to figure out where it is. Using the info provided we could see that the line has to pass (2,-7), and the x for that point is 2. Using all the info we have concluded we know that the equation of the line is x=2.
