Answer:
x = 2 or
x = -7
Step-by-step explanation:
(x - 2)(x + 7) = 0
x - 2 = 0
Add 2 to both sides
x - 2 + 2 = 2 + 0
x = 2
OR
x + 7 = 0
Subtract 7 from both sides
x + 7 - 7 = 0-7
x = -7
Therefore
x = 2 or
x = -7

Answer:
∠ABD=150°
Step-by-step explanation:
6c+12+51-c=178
5c=178-12-51
5c=178-63=115
c=115÷5=23
∠ABD=6c+12=6×23+12=138+12=150°
