Answer:
- base angles of an isosceles triangle
- angles at successive corners of any regular polygon
- angles either side of an angle bisector
- angles made by a perpendicular to a line (excluding vertical angles)
Step-by-step explanation:
When it comes to angles, the term "adjacent" means different things in different contexts. Any pair of angles in a triangle are considered to be adjacent. The base angles of an isosceles triangle are adjacent congruent angles.
Angles at successive corners of any regular polygon are congruent adjacent angles.
Angle that have a common vertex and a common side are also called adjacent angles. Angles on either side of an angle bisector are adjacent congruent angles. Likewise any non-vertical pair of angles where lines cross at right angles are adjacent congruent angles.
The answer is 90, 25, 155, 115 respectively

Answer:
C) Maria bought a magazine for $8 and 2 notebooks. She spent a total of $15. What was the cost of each notebook?
Step-by-step explanation:
The equation has twice an unknown value added to 8 with the result being 15.
<em>Here are how the answer choices compare to the equation:</em>
A) only one magazine of unknown cost is involved, not two. There is not enough information to answer this question with any equation.
B) three unknowns are involved and the question asks for the difference of their sum and 15. There is not enough information to answer this question with any equation.
C) if x represents the cost of the notebook, the equation is appropropriate to finding its cost, as asked by the question. This is the best choice.
D) only one unknown. The question makes no sense, as she bought items worth more than the amount paid.
