The question is an illustration of bearing (i.e. angles) and distance (i.e. lengths)
The distance between both lighthouses is 5783.96 m
I've added an attachment that represents the scenario.
From the attachment, we have:

Convert to degrees





Convert to degrees



So, the measure of angle S is:
---- Sum of angles in a triangle


The required distance is distance AB
This is calculated using the following sine formula:

Where:

So, we have:

Make AB the subject


Hence, the distance between both lighthouses is 5783.96 m

Okay do 4*10 and 7*10 (you get 40/70) and then do 3*7 and 10*7 (so now you've got 21/70) then add 21/70+40/70 and that's the total distance
Answer:
The last choice
Step-by-step explanation:
5^2 + 12^2 = 13^2
25 + 144 = 169
N=#
-6(n)
I think this is the answer
Answer:
2/3
Step-by-step explanation:
7/9 - 2/8 x 4/9
Reduce the fraction.
7/9 - 1/4 x 4/9
Reduce the numbers:
7/9 - 1/9
Subtract the fractions.:
6/9 > 2/3
