Acone-shaped hole is drilled into a solid cube of metal as shown. if the cube has sides of length 9 cm, what is the volume of the metal after the hole is drilled? let π ≈ 3.14 and round your answer to the nearest tenth.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

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.
