Jan's age =
years
Sister's age =
Step-by-step explanation:
Jan's age = x years
Sister's age = 2x years
Brother's age = 3x years
According to the given condition:
x + 2x + 3x = 29
6x = 29
x = 29/6
x =
years
2x = 
Therefore,
Jan's age =
years
Sister's age =
So basically you just want to find the LCM of the denominators shown, or 2 and 3.
So in this case, you could use the most inefficient method, or listing the multiples out:
2 : 2, 4, 6
3: 3, 6, 9
And as you can see, the first multiple that matches is 6. So your answer would be B, 6.

Answer:
the angle are 50, 47, 83
Step-by-step explanation:
we know that the sum of the three angles of the triangle is 180 degree
now, 4x+22+3x+26+9x+20=180
x=7
the angle are 50, 47, 83
