Answer:
yes, triangle DEF is similar to triangle DBC, BC corresponds to EF, and angle DCB corresponds to angle F.
Step-by-step explanation:
Part A: Angle D is congruent to angle D by the reflexive property. Since line BC is parallel to line EF then angle DCB = angle DFE by corresponding angles. Hence triangle DEF is similar to triangle DBS by the AA Similarity Postulate.
Part B: BC corresponds to EF because they are in the same order and the triangles listed DEF and DBC
Part C: Angle DCB corresponds to angle F since they are corresponding angles with the two given parallel lines BC and EF.
B. 16 cm
Square both 20 and 12
20x20=400
12x12=144
400-144=256
find the square root of 256
and the square root is 16
so b is 16 cm
The price of the jeans is 41 dollars and 40 cents
To solve this problem you must apply the proccedure shown below:
1. You have the following points given in the problem above:
![A(9,8)\\ B(-1,-2)](https://tex.z-dn.net/?f=%20A%289%2C8%29%5C%5C%20B%28-1%2C-2%29%20)
2. To find the midpoint, you must apply the formula that is used for calculate it. This is:
![m=(\frac{x1+x2}{2}, \frac{y1+y2}{2} )](https://tex.z-dn.net/?f=%20m%3D%28%5Cfrac%7Bx1%2Bx2%7D%7B2%7D%2C%20%5Cfrac%7By1%2By2%7D%7B2%7D%20%29%20)
Where:
![x1=9\\ x2=-1\\ y1=8\\ y2=-2](https://tex.z-dn.net/?f=%20x1%3D9%5C%5C%20x2%3D-1%5C%5C%20y1%3D8%5C%5C%20y2%3D-2%20)
3. Now, you must substitute these values into the formula for calculate the midpoint, as following:
![m=(\frac{9+(-1)}{2} ,\frac{8+(-2)}{2} )\\ m=(4,3)](https://tex.z-dn.net/?f=%20m%3D%28%5Cfrac%7B9%2B%28-1%29%7D%7B2%7D%20%2C%5Cfrac%7B8%2B%28-2%29%7D%7B2%7D%20%29%5C%5C%20m%3D%284%2C3%29%20)
Therefore, the answer is: ![m=(4,3)](https://tex.z-dn.net/?f=%20m%3D%284%2C3%29%20%20)
