Answer:
5/32768
Step-by-step explanation:
This sequence does not have a common difference, but does have a common ratio of r = 10/40 = 1/4. The first term is a1 = 40.
The general term of a geometric sequence is ...
an = a1·r^(n-1)
Then the 10th term is ...
a10 = 40·(1/4)^(10 -1) = 40/4^9 = 5/32768
The longer leg is the leg adjacent to the larger angle
so 60
length of longer leg = 4 sin60 = 2sqrt(3)
3x+y=8
y=8-3x
5x+3(8-3x)=8
5x+24-9x=8
-4x+24=8
-4x=-16
x=4
5x+3y=8
5(4)+3y=8
20+3y=8
3y=-12
Y=-4
5x+3y=8
5(4)+3(-4)=8
20+-12=8
8=8
