I believe it’s C.70 because there’s two lines on the two sides of the triangle and I belief that means they’re the same. So you would need to get 140 because 180 - 40 = 140 and since those two sides are the same you would divide 140 by 2 and get 70
Hi I would have to say 200 sorry if my answer sucks but I'm trying my best to help you :D
The most logical order is:
- The coordinates of point D and E by the midpoint formula.
- Slope of segment DE and slope of segment AC.
- Segment DE is parallel to segment AC. Slopes of parallel lines are equal.
- Length of segment DE and length of segment AC by the distance formula.
- Segment DE is half the length of segment AC by the substitution.
