Answer:
5.3
Step-by-step explanation:
Cos(68) = adjacent/hypotenuse
Cos(68) = 2/AC
AC = 2/cos(68)
AC = 5.3389343253
AC = 5.3
Answer: The lines through the pairs of points are perpendicular.
Step-by-step explanation: The lines when graphed do not have the same slope so they can not be parallel. However, when graphed the points (-3, 5) and (-1, 0) goes through the midpoint of the points (-3,1) and (2,3) meaning that the above points are perpendicular! Hope this makes sense and helps.
The equation of the line is 
Explanation:
The given equation is 
<u>Slope:</u>
Since, the equation of the line is perpendicular to the equation , then, the slope is given by
Hence, the slope is
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,
Substituting the point (-2,3) and the slope , in the above formula, we get,
Simplifying, we get,
Therefore, the equation of the line is
The length of the third side is a-2. :))
