Answer:
Using the 30-60-90 triangle to find sine and cosine
sin(60 degrees) = 2√3 4.
sin(60 degrees) = √3 2.
sin(30 degrees) = 2 4.
sin(30 degrees) = 1 2.
cos(60 degrees) = 2 4.
cos(60 degrees) = 1 2.
cos(30 degrees) = 2√3 4.
cos(30 degrees) = √3 2.
First, let's use the Distributive Property to make our equation easier to solve. Remember that the Distributive Property says the following:
Using this, we can multiply the 7 out to the and 3. This gives us:
Now, let's solve for :
We can see that there is one solution for this equation because is equal to one definite value after solving. Thus, our answer is A, one solution.
