Which is the best unit to measure the distance between califronia and new york

Miles would be the best.

Step-by-step explanation:

Miles are the largest way to measure land, so I would use that.

Miles

When measuring that far of a distance, you want to use the largest unit of measurement, because measuring in inches or centimeters is unrealistic.

Hope this helps! Good luck! :)

b.my answer is b.

brainliest

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.
