AfilCa [17]3 years ago
6 0

Answer: ? = -22.5

Step-by-step explanation:

Using a negative number to replace the ? turns the minus into a plus sign.

-21 - (-22.5) = 1.5 is the same as -21 + 22.5 = 1.5

If AD/DB = AE/EC, then line segment (?) is parallel to line segment (?) .
olga_2 [115]

Answer:

Step-by-step explanation:

In ΔABC, we have

\frac{AD}{DB}=\frac{AE}{EC}

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 \frac{AD}{DB}=\frac{AE}{EC}, 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  \frac{AD}{DB}=\frac{AE}{EC},then line segment DE is parallel to line segment BC .

Airida [17]
If you are finding the perimeter the answer would be:
$15.50
If you do 9*$1.75=$15.75
If you do 10*$1.75=17.50
When you find perimeter it’s length+length+ width+ width
This gives you $15.50
If you are finding the area the answer would be:
$157.50
To find area you do 10*9=90
Then, you do 90*$1.75=$157.50
