1. Should stay the same since you can't combine any further
2. 6x²-6x+16
60 for both
Since these angles are parallel, they are equal to each other :
6x = 5x + 10
Subtracting 5x from both sides gives us :
x = 10
Substituting this value back into both angles gives us
6x = 60
5x+10 = 60
1=point
2=line
3=line
4=line segment
5=ray
6=plane
7=plane
