Question

Find the supplement of 78⁰ and complement of 60⁰.​

Answer 1

Supplement means the sum should be 180 degrees.
So, supplement of 78 is 180 - 78 = 102 degrees.

Complement means sum should be 90 degrees.
So, complement of 60 is 90 - 60 = 30 degrees.

Answer 2

Sum of supplementary angles = 180 degree
So , let the other angle be x
78+x = 180
x = 180-78
x = 102 degree



Sun of complementary angles = 90 degree
So , let the other angle be x
60+x = 90
x = 90-60
x = 30 degree
