How to prove the identity?</h3>
Here you need to remember two things:

Here we have the expression:

By using the first rule, we can rewrite:

By using the second rule, we can rewrite:

Now if we multiply and divide by cos(x), we get:

In this way, the identity was proven.

Answer:132
Step-by-step explanation:
Use proportion
12:2=x:22
x=22*12/2
x=132
We know that the standard form of the equation is:
ax + by = c
and we are given the equation:
y = -3x + 6
<u>Converting to standard form:</u>
3x + y = 6 [adding 3x on both sides]
3x + y = 6
and we are done already!
