The measures of the angles of a triangle are shown in the figure below.
Solve for x.

x = 13

Step-by-step explanation:

All of the interior angles of a triangle add up to equal 180 degrees.

This means that if you set the expressions from your problem to equal 180, you'll get the value of x:

6x - 9 + 4x + 10 + 4x - 3 = 180        (original equation)

14x - 2 = 180                                    (combine like terms)

     +2       +2                                   (add 2 to both sides)

14x = 182

x = 13                                              (divide both sides by 14)

y=mx+b is the final answer!   : )

the correct answer is the second option
