Angles are formed by intersection of non-collinear lines, rays and planes.
<u>Part A</u>
<u>1. Contradictory Example</u>
A contradictory example to the given definition is that:
When the rays are collinear; the rays do not form an angle, but they form a line
<u>2. A more accurate definition</u>
A more accurate definition is that:
An angle is formed at the intersection of two non-collinear rays that have the same endpoint
<u>Part B</u>
<u>Example of an undefined term</u>
Undefined terms do not have a formal definition; an example is the plane.
A plane pertains to angles because it determines the parameter to be measured.

Hey there! I'm happy to help!
Let's call our fraction x.
x=5.2727272727......
We want to get rid of the repeating decimals. If we multiply our fraction by 100, we have that 100x=527.27272727.....
100x=527.2727272727....
x=5.27272727....
If we subtract these equations, the repeating stuff will be gone and we can solve for x.
99x=522
We divide both sides by 99.
x=522/99= 58/11= 5 3/11.
Have a wonderful day! :D
