Answer:
It's asking for a reflection. The point D is 5 points lower than the line, so the plot dot should be 5 points higher than the line, right above the other D point. Think of the line as a mirror.
The red dot in the attached image is the answer.
Answer:
C
Step-by-step explanation:

<span>It says to round to the nearest 10th of a foot, so your answer would be 10.2 feet.</span>
To find y you must recognize that 141+3y=180 . You know this since half of a circle is 180, and a line is basically half a circle if you arc from end point to end point.
You can then subtract 141 from both sides,
3y = 39
Then divide both sides by 3,
y=13
You would want to use 39° for 3y° since 3·13= 39.
A triangle can only contain 180°, so you would add 68 and 39 together and then subtract this from 180 to give you x.
68 + 39 + x = 180
107 + x = 180
x = 73
