The Angle HCA is equal to 52°. This is arrived at using the knowledge of the Total value of Angles in a Triangle and the Total Value of Angles in a Polygon.
<h3>
What other principles were used to arrive at the answer?</h3>
The other principles of mathematics that were used to arrive at the above answer are:
- Total Angles on a straight line;
- Total Angles on a point; and
- Line segments.
<h3>What are the Steps to the Solution? </h3>
Step 1 - Recall that we have been given Angles AHB and BAH to be 128° and 28° respectively.
We also know that:
- The sum of angles in a triangle is 180°;...................A
- The sum of angles on a straight line is 180°;.........B
- The sum of angles in a polygon is 360°; while.....C
- The total sum of angles at a point is 360°.............D
Since A...therefore:
When ∠AHB (128°) and ∠BAH are taken from 180° we have DBA = ∠28°.
By observation, we can deduce that ∠BDE, ∠CDH, ∠CEH and ∠AEH are all right-angled triangles.
Using the above, we are able to repeat this process of solving for each angle until we have ∠HCA.
To verify that our answer is correct, recall that sum of angles in a polygon is 360°
That means:
∠BDA + ∠DHE + ∠CEH + ∠HCA = 360°
That is, 90+ 128 + 90 + 52 = 360°

Complete question is;
The author uses the gas station attendant's warning to create tension by foreshadowing that ?
A. Maggie may have problems on her journey
B. Maggie may not be a good driver.
C. the attendant does not like Maggie's car.
D. the attendant does not think Maggie has enough gas
This question is taken from the book titled "A Good Place for Maggie" written by Ofelia Dumas Lachtman.
- From the book, we can see that the gas station's attendant is doubtful about the possibility of Maggie's car being able to successfully take on the difficult journey she was to embark upon. Thus, to him he felt that the car was okay but, he was of the opinion that Maggie may have gotten into trouble with the car along the journey.
- In that moment of that statement by the stations attendant, we can say that the author used a technique called foreshadowing because he gave an advanced information in the story, showing things that could later happen and which could cause tension in the mind of the reader.

Well, from what I know, I believe that it does not. I don't see how it's possible, if y = 7, how does this relate to (0,1), I don't see how it's would be possible. My guess, it would impossible.
