Answer:
∠ C = 133°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , that is
∠ A + ∠ B + ∠ C = 180° ( substitute A + B = 47° )
47° + ∠ C = 180° ( subtract 47° from both sides )
∠ C = 133°
Answer:
Option C. 2x + 20 / x² + 6x – 40
Step-by-step explanation:
f(x) = x + 16 / x² + 6x – 40
g(x) = 1 / x + 10
To find f(x) + g(x), please refer to the attached photo.
After factoring
we get 
Step-by-step explanation:
We need to factorize the polynomial:

Factorization is done by breaking the middle term such that the sum is equal to the middle value of polynomial and product is equal to product of first and last term in the polynomial.
So, Factorizing:

So, After factoring
we get
