Answer:

<h3>            x = 7 ,   y = 7√2</h3>

Step-by-step explanation:

The sum of measures of angles in triangle is 180°

so:

180° - 90° - 45° = 45°

two angles angles of the same measure, that means: x = 7

so:

      7^2+7^2=y^2\\\\y^2=7^2\cdot2\\\\y=\sqrt{7^2\cdot2}\\\\\bold{y=7\sqrt2}

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.
