The Total solution for NCERT class 6-12
If an angle is 280 lessthan its complement, find its measure?
Let the measure of any angle is ‘ a ‘ degrees
Thus, its complement will be (90 – a) 0
So, the required angle = Complement of a – 28
a = ( 90 – a ) – 28
2a = 62
a = 31
Hence, the angle measured is 310.
