A line passes through the point (4, -2) and has a slope of 1/2. What is the value of a if the point (-4, a) is also on the line?
A. -6
B. -5
C. 5
D. 6

39°

Step-by-step explanation:

For a straight line, the sum of angle is 180°

At the point where we have the 107°, the inner angle in the triangle will be 180-107=73°

68° is alternate angle to the inner angle in the triangle

Since the sum of angles in a triangle are 180°, then angle x will be

X=180-73-68=39°

Therefore, missing angle is 39°
