Answer:
m = 10
Step-by-step explanation:
- From the image given, we can tell that there are two sides for angle H for the segment IJ.
- From that we can see that angle H is a supplementary angle. A supplementary angle is an angle whose sum is 180°
- (2m+10)°+(5m+100)° = 180°
- (7m+110)° = 180°
- (7m)° = 70
- m = 10
