Answer: 110
Explanation:
I'm assuming this is for a triangle. The three interior angles always add to 180.
A+B+C = 180
A+28+42 = 180
A+70 = 180
A = 180-70
A = 110
The missing angle is 110 degrees
F(x)= -4x+9
Multiply f*x
xF=9+4x
Solve for X: -4x+xF=9+4x-4x=0
Combine like terms: -4x+4x=0
-4x+xF=9+0= 9
-9+-4x +xF = 0.
The correct answer is B.
6x*6x=36x
-8*+8=-64
Thus, our equation is 36x-64
Hope this helps!
