Given:

The given angle is 70o.

Formula used:

To find the complement of a given angle subtract the given angle from 90o, and to find the supplement of a given angle, subtract the given angle from 180o.

Calculation:

The complement of 70o is 90o−70o=20o .

The supplement of 70o is 180o− 110o=70o

Therefore, the complement of 70o is 20o and supplement of 70o is 110o.
