The three interior angles of any triangle add to 180 degress. Therefore,
180-(120 + 40) = the third angle.
So, 20 is the third angle
Angle 8 because supplementary is two angles whose sum is 180°.
He passed out 91 objects. 13 x 4 = 52 + 39 = 3 x 13
ANSWER
1. k=13
2. x=-10
EXPLANATION
The given function is

To find f(x+5), plug in (x+5) wherever you see x.
This implies that:

Expand:

Simplify to obtain

We now compare with,

This implies that:

To find the smallest zero of f(x+5), we equate the function to zero and solve for x.





The smallest zero is -10.
