Answer: sin(FGE) = 9/15
Step-by-step explanation:
sine is opposite side over hypotenuse
angle FGE is opposite of side FE
6(4.5y - 12) = 9
(4.5y - 12) = 9/6
4.5y - 12 = 1.5
4.5y = 1.5 + 12
4.5y = 13.5
y = 13.5/4.5
y = 3
Answer:
O.O
Step-by-step explanation:
First we multiply 2r*r and it gives us

.
Then -5r, + 20r = 15r
Then -5*10 gives us -50.
So the answer is:
42÷6=7 42=Perimeter 6=Sides 7=Possible lengths of the hexagon.
