Equations are like a balance scale. There needs to be an “=“
The answer is: [B]: " 60° " .
________________________________________
Because at whatever location, <span>∠2 and ∠4 are vertical angles;
</span>
and all vertical angles have equal measurements.
Given: m∠1 is 120°, and ∠1 is supplementary to ∠2 ;
then m∠1 + m∠2 = 180° .
So, m∠2 = (180 - 120)° = 60° .
As aforementioned:
m∠4 = m∠2 = 60° ; which is: Answer choice: [B]: " 60° " .

Answer: A. f(g(x)) =x and g(f(x))=x and f and g are inverses.
Step-by-step explanation:
A function <em>g</em> is the inverse of function <em>f</em> if
<em>f(g(x)) = g(f(x))=x</em>
Given: f(x)= x+4 , g(x) = x-4
f(g(x)) = f(x+4) = (x-4)+4
= x-4+4 = x
i.e. f(g(x)) =x
g(f(x))= g(x-4) = (x-4)+4 =x
i.e. g(f(x))=x
Hence, f(g(x)) =x and g(f(x))=x and f and g are inverses.
Answer:
I believe the answer is A.
Step-by-step explanation:
The missing factor in the equation is -21
<h3>What is a distributive factor?</h3>
The Distributive Property introduces the multiplication operator an existing mathematical statement that involves the addition operator.
From the complete question, the equation is given as:
Where x represents the missing factor.
So, we have:
Remove brackets
Collect like terms
Evaluate the like terms
Divide both sides by -1
Hence, the missing factor in the equation is -21
