Answer answer would be 19
Step-by-step explanation:
A triangles angles must add up to 180 degrees, and 47 and 114 add up to 161. Subtract 161 from 180 and you get 19
Answer:
Function is decreasing on (-8,infinity)
Step-by-step explanation:
The given function is 
The first derivative is given by

For the function to be decreasing, we have

Divide both sides by -2. Since, we are dividing by a negative number hence, the inequality sign will change.

Subtract 8 to both sides

Therefore, the function is decreasing on (-8,infinity)
First option is correct.
