Answer:
The position is N 65° E from light house b and S 20° E.
Step-by-step explanation:
To get the bearing we subtract the angles and how it formed.
For light house A
340 means it's remaining 20° and it's almost a complete revolution signifying that it's in the SE position.
For light house B
245 means it's remaining 25° on the inside but 65° reading from the north position. Signifying it's on the NE position.
Answer:
(a) (b)
Step-by-step explanation:
GIVEN: Suppose that the owner of a farm has of fencing available, and they would like to enclose a rectangular portion of the land to allow animals to graze along side a straight portion of a river. The animals don't like the river water, so fencing is not necessary along the river.
TO FIND: What is the largest area that they can enclose using the fencing? What are the necessary dimensions of fencing in order to achieve that area?
SOLUTION:
Let the length and width of area enclosed be
as one side of area does not require fencing, total perimeter of rectangular portion.
Area of rectangular portion
putting value of in equation
to maximize area
now,
area of rectangular portion
Hence largest area of enclosure is and length and width are
We have x + y = 140 degrees and x = 5y - 13 ;
Then, 5y - 13 + y = 140;
6y - 13 = 140;
6y = 153;
y = 153 ÷ 6;
y = 25.5 degrees;
x = 140 - 25.5;
x = 114.5 degrees;
