The answer is a. r^m - n, because when dividing indices you subtract them, like a^4 ÷ a^2 = a^2. I hope this helps!
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:
2/3 km per minute
Step-by-step explanation:
kilometers
1 1/3 - 2/3 = 2/3km
Minutes
2 - 1 = 1 minute
----------------------------
Spped
(2/3 km) / (1 minute)
2/3 km per minute
