Answer:
Shorter
Step-by-step explanation:
Since in the new map 1 cm is representing a larger area of 500m as compared to the previous map where 1cm represented 100m.
The answer is five. All you had to do is keep multiplying 8.6 until you found the correct number. Eventually you would've gotten to five.
Since a is supplementary to b, their sum is 180*.
m55+b=180
-55 -55
b=125*
