Answer:
As in this case where the adjacent angles are formed by two lines intersecting we will get two pairs of adjacent angles (G + F and H + E) that are both supplementary. Two angles that are opposite each other as D and B in the figure above are called vertical angles. Vertical angles are always congruent
Step-by-step explanation:
Your answer is -43/6
1/12(4+6x3)-9
=1/12(22)-9
=11/6-9
=11/6-54/6
=-43/6
line N has slope m = 
given a line with slope m then the slope of a line perpendicular to it is
= - 
thus line N has slope -
= 
Answer:
a positive number
Step-by-step explanation:
-(-) = +
for example, -1 * -1 = 1
? -2 -1 0 1
-1-2=-3
The answer is -3
