Step-by-step explanation:
<u>Angles and Lines</u>
We must recall:
- The sum of the internal angles of a triangle is 180°
- Two linear angles add up to 180°
The image shows a triangle and the extension of its base to form two linear angles.
Note from the triangle, angle R is what it takes to get to 180°:
From the line SQ, angle R what it takes to get to 180°. Thus:
Equating:
Subtracting 180 and simplifying:
Dividing by 19:
x=3
Answer:
y =
Step-by-step explanation:
Equation of a line has been given as,
Here, slope of the line =
y-intercept =
"If the two lines are parallel, there slopes will be equal"
By this property slope of the parallel line to the given line will be equal.
Therefore, slope 'm' =
Since, slope intercept form of a line is,
y = mx + b
Therefore, equation of the parallel line will be,
y =
Since, this line passes through a point (-6, 6),
6 =
6 =
b =
b =
b =
Equation of the parallel line will be,
y =
(0,-6), (6, -3), and (6,-6)
If you plot them on a graph there are only two point options (in green and purple) since it's a right triangle but you have to use the one that has -6 as the y value
