How many sets of perpendicular lines are in a trapezoid ?

1 set

Step-by-step explanation:

1 set=2 lines

-A trapezoid has 4 lines: top, bottom, left, and right.

The top and bottom lines is a set of parallel lines because they will never cross each other.

Now, we are left with the left and right sides. They are slanted and are not 90 degree angles, so that means that they will eventually meet if you keep drawing their lines.

This means that the left and right sides are perpendicular. Also, since 2 sides=1 set, we have 1 set of perpendicular lines.

Hope this helps!

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
