To prove this statement, start with a picture of alternate interior angles that are assumed to be congruent, but don't assume the lines are parallel. In the picture below, assume . Prove that (two parallel bars indicate parallel lines). If corresponding angles are congruentthen lines are parallel.
Well, I Don't See The Answer Choices, But The Next Step Is Most Likely To Subtract 8 From Both Sides.
For finding the perimeter of abc (triangle), we MUST need the two others coordinates of b and c
let b(1, 2) and c (2, -4)
we need to calculate the distances ab, ac, and bc
vector (ab)=(1-(-2), 2-9)=(3, -7), so its length is ab=sqrt(3²+ (-7)²)=7.61
realising the same method, we find bc=6.08, ac=13.60
so the perimeter of abc is P= ab+bc+ca=13.60+6.08+7.61=27.29
Answer:
x = 
Step-by-step explanation:
Using the midline theorem
A segment joining the midpoints of 2 sides of a triangle ia
Parallel to the third side and half the length of the third side, thus
7x - 1 = 24 ( add 1 to both sides )
7x = 25 ( divide both sides by 7 )
x =
