Answer:
Dilate circle A by a scale factor of 4.
Step-by-step explanation:
Dilating circle A by 4 would be the same as multiplying its radius of 6 by 4, which would make it 24.
The radius of circle B is 24.
Rotating it wouldn't change anything (it's a circle), and I don't think reflecting and translating show circle similarity

Answer:
6m
Step-by-step explanation:
You need to use trigonomtery: SOHCAHTOA
Since we are looking for the height, we should use the Sine rule:
Sine(37) = opposite/hypotenuse
We already have our hypotenuse which is 10
sine(37) = opposite/10m
Now we re-arrange to find the opposite(which is our height)
opposite = 10m x sine(37)
opposite = 6.018
Therefore height = 6 to the nearest metre
Hope this helps :)
