The u. s. is 3.794 million square miles approximately 65 square miles are work for food production what percent of the u. s. is work for food production

x≈17.13

Step-by-step explanation:

1.) 650000/3794000=x/100

2.) 65000000=3794000x

3.) 65000=3794x

4.) 65000/3794= 3794x/3794

5.) x≈17.13

the answer is d

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.
