Answer:
30
Step-by-step explanation:
2700/90 = 30
27/9 = 3
100/10 = 10
3*10 = 30
For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the equation that models the problem:

From here, we clear the value of x.

We subtract 30 on both sides of the equation:

Answer:
The value of the unknown number is given by:

180 - 47 = 133
The answer is the second option, 133 degrees
