Please help me with this question.

Area = 43.26

Step-by-step explanation:

There is a short way to do this.

Area = 1/2 s*t * Sin(R)

s = 14

t = 7

Area = 1/2 * 14 * 7 * Sin(62)

Area = 7 * 7 * sin(62)

Area = 49 * sin(62)

Area = 43.26

There is another way you could do this.

Use the Cos law to find r

Then use Heron's formula to find the area. Trust me, you don't want to do that.

Doing the way I suggested gives 43.19. The difference is in what I did in the rounding. But I wouldn't want to type all the numbers.

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.
