Answer:
Step-by-step explanation:
We need to check each u value to say if each one is correct...
8 u - 27
when u = 33
8 33 - 27
8 6
and it's true!
So, 33 is solution
when u = 39
8 39 - 27
8 12
It isn't true. No solution!
When u = 31
8 31 - 27
8 4
It's true and it also is a solution.
when u = 35
8 35 - 27
8 8
it's true and it also is a solution.
Answer:
The distance from the ship to the dock is approximately 5.24 miles
Step-by-step explanation:
From the parameters given in the question, we have;
The angle formed between the dock and the lighthouse = 70°
The angle formed between the dock and the lighthouse at the ship = 80°
The distance between dock and the lighthouse = 5 miles (From a similar question online)
By sine rule, we have;
Therefore, we have;
Therefore;
The distance from the ship to the dock ≈ 5.24 miles
