If a supplement of an angle is 20 more than 3 times a complement, then the measure of the angle is?

Let the angle be x
therefore,Its supplement is 180-x and its complement is 90-x
According to the problem
180-x=3(90-x)+20
=>180-x=270-3x+20
=>-x+3x=270+20-180=110
=> 2x=110
x=55

31 is prime. and it’s prime factorization is just 31.
