Mathematics
1 answer:
Tems11 [23]3 years ago
5 0

Answer:

A

Step-by-step explanation:

10 and 8 are equal

11 and 15 are equal

due to the fact that the angles 10 and 11 but also 8 and 15 are supplementary, we know that they add up to be 180 degrees

180-42=138 degrees

and this means that angle 8 will also be 138 because of what we established earlier

vichka [17]

Answer:

\frac{1}{5}\frac{in}{miles}

\frac{2}{30}\frac{in}{miles}=\frac{1}{15}\frac{in}{miles}

If the map is enlarged to 3 times its size

then

the new scale will be

\frac{2*3}{30}\frac{in}{miles}=\frac{6}{30}=\frac{1}{5}\frac{in}{miles}
