Answer:
x = 41.2
Step-by-step explanation:
Assuming the dotted line at the top is parallel to the segment with length x, it follows from the alternate interior angles theorem that the interior angle of the triangle (marked in diagram) is also 27º.
Using SOH-CAH-TOA, we get that tan(27º) = 21/x, so x = 21/tan(27º), which is approximately equal to 41.2.

Step-by-step explanation:
To write the equation of a line use the point slope formula . Find m by using the slope formula with the points.
Since the line is parallel, it will have the same slope.
Substitute m = -1/3 and (-3,-4).
