Answer:

4 9/20

Step-by-step explanation:

Convert the mixed fractions to improper fractions first:

7 1/4--> 29/4, 2 4/5--> 14/5.

Now we look for the common denominator, which is 20. So 29/4=145/20 and 14/5=56/20.

We subtract them:

145/20-56/20=89/20.

Convert it to a mixed fraction to get 4 9/20.

What is a supplementary angle??
Olin [163]
A single angle is generally not considered to be supplementary. Supplementary angles are angles that equal 180° when they are added together. For example, 70° and 110° are supplementary because they equal 180°.

However, I guess the supplementary angle can be the angle that must be added to another to total 180°. For example, 80° is the supplementary angle of 100°.
