ANSWER

f( - 9) =  7

EXPLANATION

The given function is

f(x) =  -  {x}^{2}  - 10x - 2

To find f(-9), we substitute x=-9 into the function to obtain:

f( - 9) =  - ( - 9) ^{2}  - 10( - 9) - 2

Simplify:

f( - 9) =  - 81  + 90- 2

Simplify further;

f( - 9) =  7

Each angle on a triangle would add up to 180 degrees. Since a ladder goes straight up, that angle would be 90 degrees. If you add that with the 39 degree angle, you'd get 129. Subtract that from 180 and you have your answer.
