Answer:
x = 30 degrees
Step-by-step explanation:
We are given a total angle measure of 120 degrees. It is split into two smaller angles that are denoted as 3x and x. This would mean that the two smaller angles should be equal to the measure of the total (larger) angle.
We can set up an equation for this as:
3x + x = 120
Now, we can solve for x.
4x = 120
x = 120/4
x = 30 degrees
