Answer:
w is greater than or equal to 358
3x - 10 + x = 90
4x = 100
x = 25 degrees
The answer is C and here are the steps
First, you find the biggest number that you can divide 24, 30, and 12 by. I would go with 6, because it will simplify all the numbers into the simplest forms possible in this equation. Then, divide each number by 6.
24/6= 4
30/6= 5
12/6= 2
The answer:
4 : 5 : 2
