Answer:
80
Step-by-step explanation:
If we assume the triangles are similar and are isosceles, and that BK is an altitude, then we can work the problem.
Triangle OKN will be similar to triangle BKA, so ...
AN : AK = BO : BK = 1 : 3
Then ...
AN : AK : KC = 1 : 3 : 3
In terms of ratio units, ...
AN = 1
AC = 3+3 = 6
NC = 6-1 = 5
This means NC : AC = 5 : 6. The triangle perimeters will have the same ratio.
perimeter(NMC) = 5/6·perimeter(ABC) = 5/6·96
perimeter(NMC) = 80
The answer 101. 99+100+101+102+103 = 505
Radius = Diameter ÷ 2 = 18 ÷ 2 = 9
Area of circle = πr² = π(9)² = 286 units²
Answer: 9 units²
Answer:
3,4,5 because they only need one dice to be rolled while the rest need to dice to land perfectly
Step-by-step explanation:
15 + 20 + 10 = 45 I think hope it helps
