Answer:
It's the first choice.
Step-by-step explanation:
The first term is the value of n / (2n +1) when n = 1
So first term = 1 (2 + 1) = 1/3
Second term = 2/(2(2) + 1) = 2/5
Third term = 3 / (3(2) + 1) = 3/7 and so on.
Answer:
x=1/2
Step-by-step explanation:
Using pythagoras length of the other leg = sqrt ( 8^2 - 4^2) = sqrt 48 = 4 sqrt3
the ratio of the sides of the triangle = 8 : 4 :4 sqrt3 = 2:1:sqrt3 so this is a
30-60-90 degree triangle
