The issue with using the side-splitter to solve for x is that the side-splitter theorem is used to find lengths of the sides being split by parallel lines. In this case, the x is on a line that is parallel and thus could not be solved for using this theorem.
If we created a triangle where the tops of the non-parallel lines connected, we would be able to compare the following and solve:

However, none of this would help us solve for x using this theorem.
Answer:
The answer is y=3x+2
Step-by-step explanation:
y-y=m(x-x¹)
y-5=3(x-1)
y-5=3x-3
+5 +5
y=3x+2
Answer:
35
Step-by-step explanation:
So from 7/8 = 35/40, 35 is the answer.
Any side that is greater than 7 + 7 = 14 will not make a triangle.
x > 14 will not create a triangle.
Answer:
A dashed line
Step-by-step explanation:
Because it is just a less than sign but if it was a less than or equal to it would be a solid line.
Hope That Helped :)
