Apilot flies 720 miles from dallas, texas, to his first destination. after dropping off his cargo, he flies southeast 290 miles to his second destination. if the angle formed by his trip is 125°, what is the distance he will fly from the second destination back to dallas?

Alright, lets get started.

Please refer the diagram I have attached.

Plane flies from point A to point B then point C.

We have a triangle in which two sides AB and BC known and the angle between these two lines.

We could use cosine law to find the third side AC

Taking square root both sides

b = 917.6 miles

It means plane has to fly 917.6 miles from the second destination back to Dallas. : Answer

Hope it will help :)

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
