Answer:
see below
Step-by-step explanation:
Volume is the product of the three dimensions: length, width, and height.
The numbers in the three columns need to have a product of 12. Your knowledge of multiplication tables lets you fill in the missing factors easily.
When two straight lines intersect, the pairs of nonadjacent angles in opposite posi-tions are known as vertical angles.
If a segment AB is intersected by a transversal labeled t, then ∠1 and ∠3 and ∠2 and ∠4 are vertically angles formed by the transversal t on the segment AB.
Angles ∠1 and ∠2 can be described as adjacent and supplementary angles, so .
Angles ∠3 and ∠2 can be also described as adjacent and supplementary angles, so .
Subtract from the first equation the second equation:.
Similarly you can prove that .
