Answer:
Step-by-step explanation:
First we have to assume the smaller angle.
Let,
the smaller angle is x
Since, larger angle is 4 times the measure of smaller angle.
So, the larger angle is 4x
Now, these angle are complementary.
we know,
sum of complementary angles is 90
So, we get
x+4x=90
or, 5x=90
dividing by 5
x=90/5
=18
So, smaller angle is 18
and larger angle is
18x4=72
