Answer:
C.
Step-by-step explanation:
Figure A is 5 spaces down reflected off of figure B.
The answer is b. You can find it by doing Pythagorean theorem. You know the radius and one side of the triangle, so now you solve for the other side by using that theorem. Once you have the length of the missing side you subtract it from the radius. (14.5 - 10.5).
The decimal point just moves to the right 1 digit.
Example:
100.000 ---> 10.000 ---> 1.000
The answer is 51.9 becuse 51.4 +0.5 = 51.9
