Answer:
80 degrees
Step-by-step explanation:
As it is a straight line the total angle is out of 180 degrees. And so to work it out you would at first add the two angles together. Then you would subtract that from 180 degrees to give you the missing angle.
1) Add the two angles together.
[tex]75+25=100[/tex]
2) Subtract that from 180.
[tex]180-100=80 degrees[/tex]
