David is a sophomore in high school and is studying for his United States history exam, in which he must recall all of the battles in the American Revolutionary War. At first, he begins by just trying to group all of the facts associated with each battle into his memory. When he realizes he is forgetting some battles, he begins repeatedly associating the events that occurred in each battle with the place where the battle occurred. He finds he remembers the battles more readily this way, but he is still having a hard time remembering all the facts associated with each battle. Because he continues to think this is the best way to approach learning, he continues to study in this manner. After several bad grades, he realizes that his studying technique is not working, so he asks a friend who is doing better at remembering everything how she is studying. She said she is making up stories about each battle and how each battle is connected with other battles. David tries this method and finds it was much more effective for him.
Explain how each of the following concepts relates to this scenario.

Metacognition
Method of loci
Deep processing
Rehearsal
Elaboration
Chunking
Mental set

Check below for the answers and explanations

Explanation:

Metacognition is the ability to understand and regulate one's cognitive (thinking) process. David was initially using a method to aid his remembrance of the battles in the American Revolutionary war, he understands that this method was not completely working for him and decided to employ an alternative method. He consulted a friend when he saw the imperfection in this method, and applied the suggestion given to him. This is an evidence that David was able to understand his thought process, take control over it, and regulate it..

Method of loci is a method of recalling events by visualizing their places of occurrence. The second method David employed was to associate the events that occurred in each battle with the place where the battle occurred. This exactly is method of loci

Deep processing is the process of analyzing the meaning of a word ( or groups or words) to aid recall. David's friend makes up stories for each battle and connects it with other battles. This means she has to analyze the meanings of the languages used in describing each battle before connecting them to other battle. This is deep processing. David also applies this and it worked effectively for him

Rehearsal involves constant repetition of an information to aid remembrance. It is also the constant practice and preparation for an intending event or performance. David's constant practice to aid his remembrance of the battles in the American Revolutionary War is for the purpose of excelling in his upcoming exam. This is called rehearsal

Elaboration is the process of relating an information to other similar information to enhance total remembrance. This exactly is what David's friend does, she makes up stories about each battle and relates it to other battles. This is learning by elaboration.

Chunking is the process of breaking down a large piece of information into smaller units in order to learn them in bits. This is to ensure adequate remembrance of these pieces of information. David friends sees each battle as a single unit and afterwards tries to connect the different events together. This is an example of chunking.

Mental set is the process of applying a method because they have previously worked. David asked for the method his friends was using and decided to apply it just because he knew she was doing better at remembering all of the battles.

if triangle abc is congruent to triangle def, their interior angles are congruent, because congruent parts of congruent triangles are congruent (cpctc).

that means ∠d is congruent to ∠a; ∠d is equal to 8x - 2.

interior angles of all triangles add to equal 180 degrees, so you can set the sum of these interior angle values equal to 180 and solve for x.

180 = (8x - 2) + 22 + 72

180 = 8x - 2 + 22 + 72

180 = 8x + 92

88 = 8x

11 = x

x = 11
