Find the value of x, question and choices attached above

Levart [38]

Answer:

<h2>E. 22</h2>

Step-by-step explanation:

<em>Look at the picture</em>.

The lines <em>l</em> and <em>m</em> are parallel, therefore alternate interior angles are congruent.

Therefore $\beta=50^o$

Supplementary angles add up to 180°.

Therefore

$(5x-16)+\theta=180$ <em>add 16 to both sides</em>

$5x+\theta=196$ <em>subtract 5x from both sides</em>

$\theta=196-5x$

We know: the sum of the triangle angle measures is 180°.

Therefore we have the equation:

$50+2x+196-5x=180\\\\-3x+246=180\qquad\text{subtract 246 from both sides}\\\\-3x=-66\qquad\text{divide both sides by (-3)}\\\\x=22$
