Answer:
63 degrees
Step-by-step explanation:
(180-54)/2=126/2=63
When the lines are parallel, the slope have to be the same for both and we know that the slope of line B is 5/2, so the answer would be D) 5/2
The answer is 7/1, when you want to know a reciprocal, all you do to the fraction is flip it around. Hope this Helps!
0 5
4 2
= (0 x 2) - (5 x 4) = -20
