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 =
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
