55 degrees because a line measures 180 degrees so you subtract 125 from 180
Answer:
The equivalent function: 
Step-by-step explanation:
The x-intercepts of the given function on the graph can be obtained by equating the function to zero.
This is because on the x-axis, the y-coordinate is zero.

The function that has the same x-intercepts on the graph from the given options is:

Alternate Method:
The answer can also be obtained by factorizing the question.
