because people use different things to live and thrive and it always helps to care for the earth just like how the earth cares for you.
I’m not sure why you’re having trouble with this simple question.. but I’ll help.
All you have to do is add both degrees to each other if they’re on the opposite side of the equator. (0 degrees)
And if they’re on the same side of the equator subtract the smaller number from the bigger number.
So the answers in order should be
120 degrees
130 degrees
30 degrees
Hopefully this helps!
