Vasily is flying his first solo trip. his plan is to fly round trip, 2368 miles. his flight plan factors in the wind speed of 20 miles per hour and expects that he will complete the flight in 7 hours.  at what speed is vasily flying in still air?

i belive those are the ones that are under 90 degreese.

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.
