m angle 7 is 134 degrees
Since 3x+80+9x-116=180 since 7 and 8 are supplementary. This helps you find x which equals 18. After plug in x=18 into 3x+80 and you will get angle 7 is 134.
Answer:
-4
Step-by-step explanation:
Parallel lines are lines that run across from each other but never intersect. For this to work, they must change at the same rate and have the same slant. This means parallel lines must have equal slopes; therefore, the slope of the parallel line is -4. It is also important to note that parallel lines must have different y-intercepts, or they would just be the same line.
