Is that all the question says can you give it into more details
So I can help you out
Graph g seems to be steeper than graph f. green is g. red is f.
I'm assuming you want to find the wind speed.
the ground speed against the wind is 410.
2460 / 6 = 410
the ground speed against the wind is 492.
2460 / 5 = 592
the difference is 82 mph, but you need to divide by 2 because speed is being added in one direction and subtracted in the other.
82 / 2 = 41
your final answer is 41 mph.
The total inside angles of a five sided figure needs to total:
(5-2) * 180 = 3 * 180 = 540 degrees.
Add the given angles together, then subtract that total from 540 for x:
76 + 130 + 152 + 67 = 425
x = 540 - 425
x = 115 degrees
