Answer:
Step-by-step explanation:
The sequence above is a geometric sequence.
The common ratio (r) =
The common ratio < 1, therefore, the formula for the sum of nth terms of the sequence would be:
a1 = 3
r = -2
n = 6
Plug in the values into the formula
Answer:
Approximately 15.05 ft
Step-by-step explanation:
You need to use tangent for this question.
Since tan θ =
to find the Opposite, we need to rearrange the equation to:
Adjacent × tan θ = Opposite.
So if you insert 62 for θ and 8 feet for Adjacent, you will get:
8 × tan(62) = Opposite.
and you will get approximately 15.05 feet for your Opposite side
