Answer:
The radius is: 1
Step-by-step explanation:
The equation of a circle in center-radius form is:

Where the center is at the point (h, k) and the radius is "r".
Given the equation of the circle:

You can identify that:

Then, solving for "r", you get that the radius of the circle is:

Answer:
The first one is neither: 90+89=179
The second one could be either supplementary or neither: 63+47=110, but if you add the final angle measure it would be 180
The last one is complementary: 62+29=90
