Question

If the angle from 0 degrees to A measures 20 degrees, what does the angle between A and B measure?

Answer 1

Answer:

Suplimentary angles have a sum of 180°

20+ what gives 180

This can be written algebraicaly as

20 + x = 180

To solve this subtract from both sides

X = 160

Hence, the supplement of 20°angle is a 160°angle

This can be proven as 20 + 160 =180

Supplementary angle give sum of 180
