Step-by-step explanation:
Answer:
A. No, because the preimage are not congruent.
Step-by-step explanation:
If you look, the preimage and the image are not the same size. That means I dilation occurred.
If they were to be congruent, there would have been a rotation, reflection, or translation.
A. No, because the preimage are not congruent.
Answer:
548
Step-by-step explanation:
1) Divide 137 by 0.25 (25%)
137/0.25 = 548.
To check, find 25% of 548.
(548 x 25)/100 = 137
The length of side EF is the average of the lengths of the bases AB and CD of trapezoid ABCD.
EF = (8 + 20)/2 = 14
Trapezoid EF has bases 14 and 20.
The height of trapezoid EFCD is half the height of trapezoid ABCD, or 6.
A = (B + b)h/2 = (20 + 14) * 6 / 2 = 102
Answer: The area of trapezoid EFCD is 102 square units
