a beetle is down in the ground and he digs down to find an ant. A beetle starts at 2 inches below ground level. The beetle digs 1/3 of the distance , d that the ant is below ground level. The beetle is now at 4 inches below ground level. what is the distance , d the ant is below ground level? a write an equation that best represents how to find the distance that the ant is below ground level. (b) solve the equation from part (a). show your work. what is the distance ,d that the ant is below ground level?

the diameter is 16 cm. are you a teacher?

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.
