This is what it shows for the solution. Hope this helps.
Answer:
∠B = 22°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, hence
120 + x + x + 16 = 180
2x + 136 = 180 ( subtract 136 from both sides )
2x = 44 ( divide both sides by 2 )
x = 22 = ∠B
Option C:
is the correct answer.
Explanation:
The given expression is 
We need to factor the expression.
Let us rewrite the expression as

Also, we can rewrite the term
as 
Thus, we have,

Hence, the equation is of the form,

where
and 
Hence, the factor of the expression can be written as 
Thus, the factored expression is 
Therefore, Option C is the correct answer.
