Answer:

120

Step-by-step explanation:

ABC is a straight line so it is equal to 180

ABC = ABD + DBC

180 = 2x + x+90

Combine like terms

180 = 3x+90

Subtract 90 from each side

180-90  = 3x+90-90

90 = 3x

Divide each side by 3

90/3 = 3x/3

30 =x

We want to find DBC

DBC = x+90

       = 30+90

        = 120

Where is the hole for the following function located?

For the function f(x)= x+3/(x+4)(x+3), the common polynomial given is x-3 which can be equated to zero. Hence, 0 divided 0 means a hole in the function. If x+3 = 0, the hole of the function is at x = -3. ^w^
