Apilot flies in a straight path for 1 hour and 30 min. she then makes a course correction, heading 10 degrees to the right of her original course, and flies 2 hours in the new direction. if she maintains a constant speed of 685 miles per hour, how far is she from her starting position?

The pilot makes a big triangle with her flight path. The longest side will be her distance from the start as the crow flies.

Use the Law of Cosines (deg mode on a calculator):

c^2 = a^2 + b^2 - 2ab(cos C)

C = 170 degrees (only a 10 deg correction from 180)

a = 685 x 1.5 = 1027.5 miles

b = 685 x 2 = 1370 miles

It doesn’t matter which side is a and which side is b.

Now plug in the values and solve for c. Hope this helps.

a) are muscles that have bands.

happy to

pls mark as brainliest

c.the charges if the proton and electron and gravity
