A pilot flies in a straight path at a constant speed of 740 kilometers per hour for 90 minutes from her initial position. She makes a course correction now heading 10 degrees to the right of her original course and flies along this path for two more hours at a new constant speed of 800 kilometers per hour. How far is she from her starting position?

c

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
