18a +6 - 30 = 6a-4
12a -30 =-10
12a=20
a= 5/3
32 + 2x = 84
2x = 52
x = 26

Answer:
Since angle d, a, and e are supplementary, d+a+e =180 degrees.
Given that line LK and BC are parallel
By the alternate interior angle theorem, e=c and d=b.
Substitute:
d+a+e=b+a+c=180
Since b+a+c is the sum of the angles of triangle ABC, the sum of the interior angle of triangle ABC (which could be any triangle of any size and shape) is 180 degrees.
Elevation per minute
elevationchange=-8212
timechange=214
elevation per minute=-8212/214=
-8132/214-80/214=
-38-40/107=
-38 and 40/107
answer is -38 and 40/107 ft per minute
