Answer:</h2>
Option: C is the correct answer.
C.) x = −3.8, 3
<h2>
Step-by-step explanation:</h2>
The function f(x) is given by:

and the function g(x) is given by:

Now, we are asked to find the solution of the equation:

i.e. we have to find the value of x such that both the functions are equal i.e.

Now, on solving the equation using the quadratic formula i.e. the solution of the equation:

is given by:

Here we have:

Hence, the solution is given by:

First look at the given numbers, especially 123 degrees which if you add up the other side it equals 180 degrees so:
180-123= 57
Ok now you know two sides of the triangle and you know that all the 3 sides add up to 360 degrees so:
57+75= 132
180-132= 48
Does it tell you what (x) stands for
