In the figure, lines l, m, and n are parallel. A classmate says you can use the corollary to the side-splitter theorem to find x
. explain your classmate's error
1 answer:
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:
73
Step-by-step explanation:
Put the values of the variables where the variables are, then do the arithmetic.
(2·5)^2 -3·3^2 = 10^2 -3·9 = 100 -27 = 73
