Answer:
scale factor = 
Step-by-step explanation:
Compare the ratio of corresponding sides, image to original.
AB = 6 units and A'B' = 2 units, thus
scale factor = 
=

Answer:
The two angles are 69° and 21°.
Step-by-step explanation:
Write out the expression:
let x and y be two angles that are complementary and the sum of their measures is 90°
-> x° + y° = 90°
if one angle is 6º more than three times the other angle:
-> x° = 6° +3y°
Plug x = 6+3y into x° + y° = 90°
6° + 3y° + y° = 90°
Solve for y
4y° = 84°
y° = 21°
Plug y into x° + y° = 90°
x° + 21° = 90°
Solve for x°
x° = 90° - 21° = 69°
Answer:
she needed to add instead of subtract to find x so x should be 61
