The <u>correct answer</u> is:
A) A perpendicular line to one side of a triangle.
Explanation:
The converse of the triangle proportionality theorem states "<span>If a line divides two sides of a triangle proportionally, then that line is parallel to the third side."
The AA similarity theorem is part of this, as we are looking at the ratios of the sides.
Proportionality of the sides is part of this, as it is stated in the converse.
A parallel line to one side of a triangle is part of this, again as it is stated in the converse.</span>
Answer:
a=7
Step-by-step explanation:
first subtract 4a from each side
6a-4a-8=6
than add 8 to each side
6a-4a=6+8
combine like terms
2a=14
divide both sides by 2
a=7
