The correct question is
If a and b are parallel lines, and m∠3 = 128°, what is the measure of ∠8?
see the attached drawing
we have
m∠3 = 128°
m∠3 = m∠7---------------- > Corresponding Angles
180°=m∠7+m∠8---------- > <span>Supplementary Angles
therefore
</span>m∠8=180°-128°=52°
the answer is the m∠8 is 52°
Answer:
-5x - 2
Step-by-step explanation:
Y-2= -1/2(x+6)
Y-2= -1/2x - 3
Answer is:
Y= -1/2x -1
So your answer is A
Since it's perimeter, you're adding. the expression would be x + 2 4/5
