Answer:
the information is in the theorem itself and to prove it set up an equation in the same format the theorem uses and test it.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Recall that the notation: 
is the same as: 
which means the value of the function f when you give it as input the value obtained by evaluating g(12).
Therefore, we need to start finding what g(12) is using the definition :
and evaluating it as x = 12.
So now we use this answer "2" as input for f(x):
Therefore,
Step-by-step explanation:
m < QRS = m < URS + m < QRU
30x - 4 = 60° + 15x - 4
15x = 60°
X = 4°
<u>m < QRS</u> = 30 * 4 - 4 = <u>116°</u>
The answer would be y=-3/4x-3
