Answer: 
Step-by-step explanation:
Let us first represent the ratio.
3
Now we need to convert 3
into a improper fraction.

Now it is in its simplest form.
The final answer is 
Check out the attached image. I drew what I think your book is showing. The figure on the left is triangle ABC without any extended segments. The figure on the right has segment AB extended shown in red. This forms the exterior angle x
The rule that connects x, y and z together is the remote interior angle theorem. It says that adding two interior angles is going to be equal to the exterior angle that is not touching either interior angle. The "remote" part means "far away" so just think of the two angles that are furthest way or not touching the exterior angle in question.
In terms of algebra, the rule is
x+y = z
Answer:
The one that has the value of one.
Step-by-step explanation:
The square has 4 right angles, the rectangle has both pairs of opposite angles that are congruent, and the rhombus has angles where the sum is 360 degrees. hope this helps!!
