First of all, triangles angles add up to 180 degrees.
BCD=120. To find BCA subtract 180-120 to get 60 degrees.
We know what ABC is, it equals 85, so far we have 2 angles.
Lets add them up, 85+60=145
Since the angles must add up to equal 180 we're going to subtract 180-145
Which equals 35, BAC=35 degrees.

Answer:
x = -8, x = -4
Step-by-step explanation:
Adding a number and its opposite gives a result of 0. That is, x+8 will be 0 when x = -8, because -8 +8 = 0.
Likewise, x+4 will be zero when x = -4, because -4 +4 = 0.
The values of x that make (x+8)(x+4) = 0 are -8 and -4.
