For this exercise you need to remember the following Trigonometric Identity:

You must observe the figure given in the exercise.
You can notice that the given triangle EFG is a Right triangle (Right triangles are defined as those triangles that have an angle that measures 90 degrees).
So, you can identify in the figure that:
So, knowing these values, you can substitute them into
and then you must evaluate (Remember to round the result to the nearest hundreth).
Therefore, through this procedure you get:

Answer:
Step-by-step explanation:
3x+2y=7
Simplifying
3x + 2y = 7
Solving
3x + 2y = 7
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
3x + 2y + -2y = 7 + -2y
Combine like terms: 2y + -2y = 0
3x + 0 = 7 + -2y
3x = 7 + -2y
Divide each side by '3'.
x = 2.333333333 + -0.6666666667y
Simplifying
x = 2.333333333 + -0.6666666667y
