Step-by-step explanation:
The scale factor of the dilation is

.
Notice how one unit of Q'P' can take up 3 units of QP.
Answer:
20
Step-by-step explanation:
Those angles are the same so you can put them in an equation like this:
x + 60 = 4x
Then you subtract x from both sides to get variables on one side and constants on the other:
60 = 3x
Now divide by three to find what just x is:
20 = x
And there you go <3
Answer:
Step-by-step explanation:
Assuming it has no spin
KE = ½mv²
KE = ½(12)10²
KE = 600 J
