Each sheet of metal on a roof is parallel to the rest of the sheets of metal. If the first sheet of metal is perpendicular to th
e top line of the roof what can you conclude about the rest of the sheets of metal?

Answer:
The sheets of metal are all perpendicular to the top line of the roof.
Step-by-step explanation:
The perpendicular transverse theorem shows that in a plane, if one line is perpendicular to one of two parallel lines, then it is perpendicular to the other line as well.
Based on that theorem, we can conclude that the sheets of metal are all perpendicular to the top line of the roof.

Answer:
10%
Step-by-step explanation:
First, get the drop in value by deducting the price this year from last year's price.
Value decrease=$52.00-$46.80=$5.20
To express it as a percentage, we divide it by the original price which was $52.00 then multiply by 100 hence the percentage decrease will be
Therefore, the price decreases by 10%
