Answer: A) 46</h3>
Explanation:
The angles shown are same side interior angles.
For line L to be parallel to line M, the same side interior angles must be supplementary, or they must add to 180.
28+(3x+14) = 180
28+3x+14 = 180
3x+42 = 180
3x = 180-42
3x = 138
x = 138/3
x = 46
Just isolate f.. buy getting it alone on one side or the other
A quadrilateral always has interior angles that add up to 360 degrees.
60 degrees because it is an equilateral triangle. Hope this helps and pls give thanks!!
