(5x+15)o = 45o

It seems like you have provided a list of angles. I'm not sure what you would like me to do with these angles. Could you please provide more information or specify your question?

To solve the given equations, we need to find the value of 'o' that makes the expressions equal. Let's go through each equation one by one:

1) (5x + 15)o = 45o
To solve this equation, we need to equate the coefficients of 'o' on both sides.
5x + 15 = 45
Subtracting 15 from both sides:
5x = 30
Dividing both sides by 5:
x = 6

2) 45o
There is no equation to solve here. It's simply an angle measurement of 45 degrees.

3) 60o or 60 o
Similar to the previous case, this is an angle measurement of 60 degrees. There is no equation to solve.

4) 120o or 120 o
Again, this is an angle measurement of 120 degrees. No equation needs to be solved.

5) 125o or 125 o
Once again, this is an angle measurement of 125 degrees. No equation needs to be solved.

In summary, the only equation that needed to be solved was the first one, where the solution was x = 6. The rest are just angle measurements.
