The answer would be D) dilated by a scale factor of 3
Proof :
A is at (-2, 1), A' is at (-6, 3) Try multiplying -2 by 3 = 6, 1 x 3 = 3.
I hope this makes sense and helps.
since the triangles are similar
angle DEC = 60 degrees
3 angles inside a triangle equal 180 degrees
BAC = DCE = 64
CBA = EDC = 56
DEC = 180 -56 -64 = 60 degrees
used angle-angle theorem
Answer:Example1: 2 and 2 1/2
The mark that is closest to the right end of the glue stick is for 2 1/2 inches.
Answer on last part is 2 1/2 inches
Example 2: 1 2/4 and 1 3/4
The mark that is closest to the right end of the paper clip is for 1 3/4
Answer on last part is 1 3/4
