-- Supplementary angles add up to 180 degrees.
48 + S = 180
S = 180 - 48 = <em>132 degrees</em>
-- Complementary angles add up to 90 degrees.
48 + C = 90
C = 90 - 48 = <em>42 degrees</em>

Answer:
72 houses.
Step-by-step explanation:
We are told that a postal worker can deliver the mail to 18 houses in 15 minutes.
Let us find numbers of mails delivered by postal worker per minute.


Since we know that 1 hour equals 60 minutes, so we will multiply 1.2 by 60 to find the number mails postal worker will deliver in 1 hour.


Therefore, the postal worker will be able to deliver mails to 72 houses in 1 hour.
