The measure of an angle is 49.2°. What is the measure of its complementary angle?

40.8°

Explanation:

Given that,

The measure of an angle is 49.2°.

We need to find the measure of its complementary angle. We know that for a complementary angle, the sum of two angles is equal to 90 degrees. So,

a+b = 90

49.2+b = 90

b = 90-49.2

b = 40.8°

So, the measure of its complementary angle is 40.8°.

ther isnt a list

explanation:

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.
