Answer:

The Answer is : 60, 90, 30

Step-by-step explanation:

The sum of an angle in a triangle is 180'

        x + (x + 30) + (x - 30) = 180'

        x + x + 30 + x - 30 = 180'

collect like terms

        3x + 30 - 30 = 180'

        3x = 180'

         x = \frac{180'}{3}

         x = 60

So therefore, where x = 60

      x = 60

      x + 30 = 60 + 30 = 90

      x - 30 = 60 - 30 = 30

The Answer is : 60, 90, 30
