Answer:
D. Yes, two sides are perpendicular, and the side lengths fit the
Pythagorean theorem.
Given -:
EF = 2X-7
FG = 4X-20
EG = 21
FIND OUT
EF =?
FG = ?
To proof
as given in the question
we have the value of EF = 2X-7 , FG = 4X-20 and EG = 21
Thus we have
EG = EF + FG
21 = 2X-7 + 4X- 20
21 = 6x - 27
48 = 6x
x = 8
Hence proved
Now put this value

Now

Hence proved
Answer:
2 sellioutions
Step-by-step explanation:
idk
Count from each point to the x-axis across and go back out the same number on the opposite side of the x-axis
For instance from point d to the x axis is 2 so now start on the xaxis at -5,0 and go up 2 more so the new point for point D would be -5,2
