Answer: 1) 36°
2) Tasman Sea
Explanation:
1) As degrees are on base 60 we have
-15' to 36 ans +45' to 37°
As 45'>15', the nearest degree is 36°
2) Those are coordinates of latitude and longitude.
You can see on any map that these coordinates take you to Tasman Sea, between Australia and New Zeland.
