Answer:
3(2x-y+4)
Step-by-step explanation:
find the greatest common factor from all of them..which is 3
and then divide each number by it
3(2x-y+4)
1. 90°
2. 25°
1. A straight line has an angle of 180°, and if one part of it measures 90°, then that means the other part has to measure 90°.
2. Again, a straight line measures 180°, and if one part measures 155°, the other part must measure 25° in order for the entire angle to measure 180°.
Hope this helps, and please consider marking branliest.
