Answer:
x = 22.5°
Step-by-step explanation:
Angle BED ≅ angle EBC = 6x, so angle BEA = 4x. The angles FEB and BEA form a linear pair, so we have ...
4x +4x = 180°
x = 22.5° . . . . . . divide by 8
_____
BED and EBC are "alternate interior angles" with respect to transversal BE crossing parallel lines DE and AC.
Because α varies directley to β

(k = constant)
α=7 when β=2
7= 2k
k=
so when α=21
21=

b
b= 6
Answer:
7

12-(-3)-2(4)
12-(-3)-8
15-8=7
Answer:
2y = -x + 7
Step-by-step explanation:
y = -1/2x + 7/2 (Multiply by 2)
2y = -x + 7
