Answer:
Step-by-step explanation:b
Answer:
72 degrees
Step-by-step explanation:
To determine the value of DBC, we first have to determine the value of q
Angle on a straight line = 180 degrees
7q - 46 + 3q + 6 = 180
10q - 40 = 180
collect like terms
10q = 180 + 40
10q = 220
q = 22
Substitute for q in angle dbc
3(22) + 6 = 72 degrees

for
ax=0
assume x and/or y=0
we have
(3)(-4)(x)=0
since
3≠0
-4≠0
thefor
x=0
answer is D
