Answer:
193.53 miles
Step-by-step explanation:
Please see the diagram for understanding of how the angles were derived,
Applying Alternate Angles, ABO =77 degrees
The bearing from B to C is 192=180+12 degrees
Subtracting 12 from 77, we obtain the angle at B as 65 degrees.
We want to determine the boat's distance from its starting point.
In the diagram, this is the line AC.
Applying Law of Cosines:
The distance of the boat from its starting point is 193.53 miles (correct to 2 decimal places).

sorry i dont know this this is very hatd question necause i cant have studied
Answer:
X =30/7
Step-by-step explanation:
The first way would be something like:
-7x + 10 = -20. The first thing we would do is to subtract 10 from both sides.
Therefore,
-7x+10-10=-20-10
Simplified, we get
-7x=-30
Remove the negative symbols
7x =30
x=30/7
Second example:
10=7x - 20
Add 20 to both sides.
10+20=7x-20+20
Simplified,
30=7x
x = 30/7
Answer:
the correct answer is c
Step-by-step explanation:
because we use formule when we write a equation
Answer:
m=5
Step-by-step explanation:
Let the number be represented by m.
Then twice the number m is represented as 2* m or 2m.
3 less than twice the number m = 2m -3
As per the question this value is 7.
Representing this in equation format:
=> 2m-3 = 7
=> 2m = 7+3 = 10
=> m= 10/2 = 5
Hence the number m is given by 5.
Verification:
Twice the number = 2* 5 = 10
3 less than twice the number m = 10 -3 = 7
This is the same as 7 as per the requirement.
