What is the value of x.

charle [14.2K]

Answer:

$x=13$

Step-by-step explanation:

The angle on a straight line is always 180 degrees.

Thus,

$(12x-26)+50=180$

Remove the brackets:

$12x-26+50=180$

$12x+24=180$

Subtract 24 from both sides:

$12x+24-24=180-24$

$12x=156$

Divide both sides by 12:

$\frac{12x}{12}=\frac{156}{12}\\$

$x=13$
