Answer:
The equation of required line is y=2x+2.
Step-by-step explanation:
The slope intercept form of a line is
.... (1)
Where, m is slope and b is y-intercept.
The equation of given line EF is
.... (2)
From (1) and (2), we get
The slope of the line is 2 and y-intercept is 1.
The slope of parallel lines are same. So, the slope of required line is 2.
The line passes through the point (0,2). It means the y-intercept of the line is 2.
Substitute m=2 and b=2 in equation (1), to find the equation of required line.
Therefore the equation of required line is y=2x+2.

Answer:
39 degrees
Step-by-step explanation:
- by seeing the diagram in the attachment, we can see that the angles UWV and VWX are on straight line or, their sum makes 180 degrees.
- we also know that sum of the angles in a triangle is 180 degrees.
by using the first statement,
UWV + VWX = 180
UWV + 6x-3 = 180
UWV = 180+3-6x
= 183-6x
by using second statement,
UWV+WVU+VUW=180
substituting the values,
183-6x+2x+5+x+13=180
201-3x=180
substracting 180 from both sides,
21=3x
dividing both the sides by 3,
7=x
the angle VWX=6x-3
substituting 7=x,
VWX=6(7)-3= 39.
