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.

Answer:
(a) The system of the equations has no solution.
(b) The system of the equations has many solutions
Step-by-step explanation:
(a) To find the solutions of the following system of equations you must:
Multiply by 2:
Subtract the equations
0 = -3 is false, therefore the system of the equations has no solution.
(b) To find the solutions of the system you must:
Isolate x for
Substitute into the second equation
The system has many solutions.
Isolate y for
