Answer:
5. reduction 6.enlargement
Step-by-step explanation:
if the scale factor is greater than one (for example) 2 then it will enlarge, but if the scale factor is less than one, it is reduced.
An in #5, from A to B the rectangle goes from bigger (A) to smaller (B) so it must have a smaller scale factor in order to reduce ,and in #6 A is smaller and B is bigger which goes back to the concept of it must have a bigger scale factor in order for it to enlarge. But all in all you can see in #5 A. is the bigger rectangle so in order to become the rectangle in B. it must reduce.
Answer:
∠ 5 = 151°
Step-by-step explanation:
A linear pair are supplementary, that is sum to 180°
∠ 5 = 5 ∠ 6 + 6 , thus
∠ 5 + ∠ 6 = 180, that is
5 ∠ 6 + 6 + ∠ 6 = 180
6∠ 6 + 6 = 180 ( subtract 6 from both sides )
6 ∠ 6 = 174 ( divide both sides by 6 )
∠ 6 = 29°
Thus
∠ 5 = 180° - 29° = 151°
I believe it’s c.
Hope this helps
