Answer:
The answer is 4.
Step-by-step explanation:
1. find the factors of 16(1,2,4,4,8,16) and of 28(1,2,4,7,14,28)
2. find the highest factor of the two Factored #.(4)
Paralell has same slope
y=mx+b
m=slope
y=1/2x+b
find b
(x,y)
(4,0)
x=4
y=0
0=1/2(4)+b
0=2+b
minus 2 both sides
-2=b
the equaiton is
y=1/2x-2
or
x-2y=4
The answer is B. The angle next to 100 degrees would be 80 as the angles are supplementary. Then you would add 80 + 70 = 150. All the angles in a triangle add to 180, thus making the "x" angle 30 due to 180 - 150.
Hope this helped :))
