How fast the distance between them decrease is 16mph
<h3>How to calculate the speed of an object?</h3>
Given the following parameters
Speed of the hiker = 6mph
If is it 3/11 the rate of a cyclist, then the rate of the cyclist will be:
6 = 3x/11
3x = 66
x = 22mph
Distance between them = 22 - 6
Distance between them = 16mph
Hence how fast the distance between them decreases is 16mph

Supplementary is when two angles together add up to 180°, and complimentary is when they add up to 90°.
The first angles together make 90°, so they are complimentary, and they are next to each other so they are adjacent, so it is B.
The second angles are 60°, and they ardent vertical so they are none of these. The third angles add up to 180° so they are supplementary, so it is D.
The fourth angles are a right angle, and you can see by the little square at the point. And right angles are always 90°, so all you have to do is 90-55.1, and that gives you 34.9, so x=34.9, so it is A.
The fifth angles together make a straight line, and a straight line is 180°, so 180-72=108, so x=108, so it is D.
