Answer:
.
Step-by-step explanation:
As we know ,
The slope of a line that passes through
and
is given by :

The slope of a line that passes through (1 , 7K), and (-3,5K) =

Hence, the slope of the given line is
.
Angle e = x angle d = 5x supplementary means they add up to 180
x + 5x =180
6x = 180
6x/6 = 180/6
x = 30
so angle e = 30 and angle d = 5(30) = 150
It would be the first answer. Bubble. I don't know what you call it. But yeah, it's the first one.
Yes it is the answer that is last on the list because it is that answer
X-16=-8
Add 16 on both sides
x=-8+16
And solve; your answer will be
x=8
