Answer:
x = 45
Step-by-step explanation:
x and 3x are adjacent angles and the form a straight line. Their sum will be 180 degrees
x +3x = 180
Combine like terms
4x = 180
Divide each side by 4
4x/4 = 180/4
x =45
The probability of it being greater than one on a six sided die is 5/6 or 5:6
Just simplify them to a decimal by dividing the numerator by the denominator.
