The table below shows the amount of money needed to buy certain amounts of fabric. Fabric Cost Yards of Fabric Total Cost 3 $5.2

Answer: $21
Step-by-step explanation:
From the given table, it can be seen that
The cost of 3 yards of fabric = $5.25
Then the cost of 1 yard of fabric =
Now, If the price is the same for each yard then the cost of 12 yards of fabric =
⇒ The cost of 12 yards of fabric = $21
Therefore, If the price is the same for each yard then the cost of 12 yards of fabric = $21

The sum of the inner angles of any triangle is always 180°, i.e. you have
In the particular case of an equilater triangle, all three angles are the same, so
and the expression becomes
which implies
So, if you rotate the triangle with respect to its center by 60 degrees, the triangle will map into itself. In particular, if you want point A to be mapped into point B, you have to perform a counter clockwise rotation of 60 degrees with respect to the center of the triangle.
Of course, this is equivalent to a clockwise rotation of 120 degrees.
Finally, both solutions admit periodicity: a rotation of 60+k360 degrees has the same effect of a rotation of 60 degrees, and the same goes for the 120 one (actually, this is obvisly true for any rotation!)
