Answer: 3
Step-by-step explanation:
Answer:
x = 8
x = -8
ACB=44°
DCE=35°
BCD=101°
ACB is a triangle and all triangles are 180 degrees
78+58=136
180-136=44
DCE is also a triangle
85+60=145
180-145=35
a straight line is 180 degrees, we already know what the other two is.
35+44=79
180-79=101
is shown in the graph below.
of the quadratic equation 
is negative
