Answer:
Step-by-step explanation:
In ΔABC, we have

The Converse of the basic proportionality theorem states that if a line divides two sides of a triangle in same ratio then the line must be parallel to the third side.
Now, it is given that
, this implies that line segment DE divides AB and AC in the same ratio.
Thus, by converse of basic proportionality theorem
line segment DE= line segment BC.
Therefore, if
,then line segment DE is parallel to line segment BC .
Step-by-step explanation:
u can u sue math_way just take out the under score
I would divide 120 by 6 and get 20
It would take 20 hours
300/15= 20
The error.....Kelvin just figured the 60% markdown cost...not the final price
the final price would be : 30.65 - 0.60(30.65) = 30.65 - 18.39 = 12.26
so 12.26 is the final price
or another way to do this is : if it is marked down 60%, then u r actually paying 40%......0.40(30.65) = 12.26
