Question

The measure of an angle that is 18 o is less than its complement is a) 54 o b) 64 o c) 36 o d) 38 o

Answer 1

sum of any two angles is 90 degrees then the angles are called complementary

if one angle =x

second angle = x-18

x+x-18=90

2x=90+18
2x=108

x=108/2

x=54
second angle =x-18

=54-18
=36
