Answer:
For 1st:

For 2nd:


Explanation:
In geometry, two angles are said to be supplementary angles if their measures add up to 180°.
Two angles are said to be complementary angles if their measures add up to 90°.
In First Picture:
We need to find complementary to:
Since complementary angles measure 90°.
So,
Complementary to:
are:

Here:


In Second picture:
We need to find supplementary to:
Since supplementary angles measure 180°.
So,
Supplementary to:
are:


Note: Angles on a straight line are supplementary:
