The angle between latitudes 30oS and 13oN is
17o
33o
43o
53o
Explication
The angle between 2 latitudes one in northern hemisphere and the other in southern hemisphere and the other in southern hemisphere is the sum of their latitudes.
∴ Total angle difference = (30 + 13) = 43o
∴ Total angle difference = (30 + 13) = 43o
