Question

the supplementary angle of half of 90 degree is

Answer 1

Half of 90 degree is 45 degree.
Two angles are called supplementary if their sum is equal to 180 degree.
So, let the supplementary of 45 be x
Acc to the que
x+45=180
x=180-45=135
So 135 is supplementary of half of 90 degree

Answer 2

the ans is 135degree
because half of 90 degree is 45
adding 135 with 45 will guve us supplementary angle
so the supplementary angles are 135 and 45(given)
