A If one angle of a linear pair of angles is 75°, find the other angle.
15°
O 105°
0 75°
35°

105°

Explanation:

Two angles are linear if their angle measures add up to 180°. (This is also known as vertical angles.)

If we know the measure of one angle, we can easily find the measure of the other, assuming x is the missing angle:

Hope this helped!

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
