The midpoint is just the average of the endpoint coordinates.
(6,6)=((8+x)/2, (9+y)/2)
(12,12)=((8+x), (9+y))
(4,3)=(x,y)
So the coordinates of R are (4,3)
Can you take a picture of the question so I can solve it
I think the smallest sides correspond to the smallest angle measurement. So the smallest side would be UT and then VT and then UV.
35 tens
tens = 10 ones = 0.1 hundreds
35 tens = 350 ones = 3.5 hundreds
So 35 tens = 3.5 hundreds
