744/1000 would be your answer
Number of darts that hit the bull's eye = 15 x 40/100 = 6
Number of darts that did not hit the bull's eye = 15 - 6 = 9
D (2 and 4), vertical angles oppose eachother, and are always congruent (identical).
5.575 because you would need to add half of 0.05 which is 0.075
I think this right : )
The first triangle has a perimeter of 4+6+10 = 20.
The 2nd longest side is 6/20 = 3/10 of the perimeter. In the larger triangle, the 2nd longest side will have length (3/10)*60 = 18.
_____
These side lengths mean the "triangle" is a line segment. That is, it has zero area.
