Answer:

Step-by-step explanation:
Given
and 
Required
The relationship between them
and 
From the question, we understand that
and
are supplementary
Supplementary angles add up to 180.
So, the relationship between
and
is:

The answer is 2 1/5 because 1 3/8 is =11/8 TIMES 2/5 IS 2 1/5

Check the picture below.
you can pretty much count those lengths off the grid.
recall that A = 1/2 bh.
Check the picture below, keeping in mind that opposides sides and interior angles in a parallelogram are congruent.
The value of p would be 40. This is because the ratio of p:q = 10:5. this could be simplify into p:q = 2:1. Applying the ratio p:20 = 2:1, P=40.
