Does anyone know how to do this? How do you know if you do just 150=4x-6 OR 150+4x-6=180? I don’t understand how to tell which o
ne to use and I’m really struggling

Given :
- A(-6, -10)
- B( 2, 5)
Let's solve by using midpoint formula :
Hope Helps! :)
Answer:
A
Step-by-step explanation:
We want to solve the equation:
To do so, we can rewrite the equation.
Recall the double-angle for sine:
By substitution:
Distribute:
We can subtract 3cos(x) from both sides:
And factor:
Hence, our answer is A.
*It is important to note that we should not divide both sides by cos(x) to acquire 10sin(x) = 3. This is because we need to find the values of x, and one or more may result in cos(x) = 0, and we cannot divide by 0. Hence, we should subtract and then factor.
