The answer would be C. If you simplify the 12/9 by 3 it would simplify to be 4/3 and 4/3 = 4/3. You can also cross multiply 4/3 = 12/9. 4(9) = 12(3) both would equal 36 so they would be proportional.
This is true a polygon with 12 sides is called a dodecafon.
Answer:
1008
Step-by-step explanation:
like the 2nd picture we split it in 3 rectangular prism
=6*7*8=336
=6*7*8=336
=6*7*8=336
V=336+336+336=1008
21. D. is the answer. Angle Q is 75 degrees. X=30. The triangle is an isosceles angle so therefore there are 2 angles are congruent to each other, Angle R and Angle Q. All three of the angles should add to 180 degrees.
Answer:
Step-by-step explanation:
