Answer:
183.6 miles
Step-by-step explanation:
Kindly check the picture attached for the solution diagram
Using the cosine formula (Diagram has two sides and an included angle)
x² = y² + z² - 2zy * cosX
x² = 150² + 60² - 2(150*60) * cos115
x² = 22500 + 3600 - 18000 * −0.422618
x² = 22500 + 3600 + 7607.1287
x² = 33707.128 miles
x = √33707.128
x = 183.59501
x = 183.6 miles
Answer:
In order to determine if two lines are parallel, perpendicular, or neither, look at their slopes. If the lines have the same slope, they are parallel. If the slopes are opposite reciprocals, then they are perpendicular. If the slopes of the lines are not any of those, then they are neither.
Parallel line:
Perpendicular line:
Neither:
Step-by-step explanation:
In order to determine if two lines are parallel, perpendicular, or neither, look at their slopes. If the slopes of the two lines are the same, then they are parallel. If the slopes of the two lines are opposite reciprocals, then they are perpendicular. If the slopes of the lines are not any of those, then they are neither.
The equation is in slope-intercept form. The y is isolated and it's in
format. Whenever an equation is in slope-intercept form, the
, or the coefficient of the x-term, represents the slope. So, the slope of the given line is
. Therefore, use the rules listed previously to find lines that are parallel and perpendicular.
Parallel lines have the same slope, so an example of a parallel line would be .
Lines that are perpendicular have slopes that are opposite reciprocals, so an example of a perpendicular line would be .
Lines that are neither do not fall into either of those categories, so an example of a line that is neither would be .
