Question

find the angle, if its supplement is 3 times of its complement :

Answer 1

let one angle be x
now
supplement of angle x is (180-x)
complement of angle x is (90-x)
according to the question..
(180-x)=3(90-x)
180-x=270-3x
2x=90
x=45
therefore the angle is 45

hope this helps:p

Answer 2

hi friend
let the angle be x
its compliment be (90-x)
and its supplement be(180-x)
ATQ 180-x=3(90-x)
         180-x=270-3x
          3x-2x=270-180
            2x= 90
              x= 45
so the required angle = 45°
