<h3>Given</h3>
A geometric sequence such that ...

<h3>Find</h3>

<h3>Solution</h3>
We can use the ratio of the given terms to find the common ratio of the sequence, then use that to find the desired term from one of the given terms. We don't actually need the common ratio (-2). All we need is its cube (-8).

Since s and t are complimentary, that means ∠s + ∠t = 90
From the picture, we also know that ∠t + ∠LGM = 90
Set them equal to each other:
∠s + ∠t = ∠t + ∠LGM, solve:
∠s = ∠LGM
Now using the fact that tangent = opposite/adjacent:
tan (∠s) = 
tan (∠s) = 
Set them equal to each other to get:
= 
Solve:

Part B:
Using tan (∠s) = 
We get:
meters
Hope that helps!
Answer:
the 3rd option (36, 48, 60)
Step-by-step explanation:
i used a²+b² = c²
Answer:

Step-by-step explanation:
The spinner is independent (the total won't be effected)
we know there is 2 whites with 8 coloured option.

we want the probability of getting two whites.

there is 3 ways to work out probability, fraction, decimal and percentage (i'd personally say fraction is the most easiest)
Answer:
it would be 0.0125 i guess
