Question

the number of attempts on this question is limited before you are restricted from further attempts. answer attempt 1 out of 2 $k =$

Explanation:

Step1: Note the angle - relationship

The two angles are supplementary (linear - pair), so their sum is 180°.
$(3k + 8)+112=180$

Step2: Simplify the left - hand side

$3k+8 + 112=3k + 120$
So, $3k+120 = 180$

Step3: Isolate the variable term

Subtract 120 from both sides:
$3k=180 - 120$
$3k = 60$

Step4: Solve for k

Divide both sides by 3:
$k=\frac{60}{3}$
$k = 20$

Answer:

20
