Answer:
m∠7=34°
Step-by-step explanation:
m∠2=m∠8=146° because alternate interior angles are congruent.
m∠7=180-m∠8=34° because it is a linear pair.
Answer:
31.2
Step-by-step explanation:
i googled it
Make each equation equal to each other, then solve for x.
-x+2=4x+7
-x-4x=7-2
-5x=5
X=-1
Sub x into one if the y formulas to find y
Y=4x+7
Y=4(-1)+7
Y=-4+7
Y=3
See my picture for how to graph the points.
Hope this helps!
You know they are parallel because the lines will never intersect or meet. (Two straight lines usually mean it is parallel)
