It is known that ∠α = 35 ° 42'36 '', and the complement of its remainder angle is degree Correct answer, add 5 points!!!

It is known that ∠α = 35 ° 42'36 '', and the complement of its remainder angle is degree Correct answer, add 5 points!!!

Remainder angle = 90 - a = 54 ° 17 ′ 24 ″
Between degrees, minutes and seconds is 60 to one;
Complementary angle = 180 complementary angle = 180-54 ° 17 ′ 24 ″ = 125 ° 42 ′ 36 ″
