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 .
Answer:
x + 24
Step-by-step explanation:
Which of the following has the least steep graph? A. y = 3x - 16 B. y = 2x + 7/15 (7/15 fraction) C. y = 1/2x + 3 (1/2x fraction) D. y = x + 24
The answer should be C, 21. I’ll attach a picture for explanation.
Use the pythagorean theorem:
EF² +DF²=DE²
EF²=18²-12²=180
EF=√180
E is the answer.
