Question

question solve for the value of a. answer attempt 2 out of 2 a =

Explanation:

Step1: Set up equation

Since the sum of the two angles is 180° (linear - pair of angles), we have the equation $104+(8a - 4)=180$.

Step2: Simplify the left - hand side

Combine like terms: $104-4 + 8a=180$, which simplifies to $100+8a=180$.

Step3: Isolate the variable term

Subtract 100 from both sides: $8a=180 - 100$, so $8a=80$.

Step4: Solve for a

Divide both sides by 8: $a=\frac{80}{8}=10$.

Answer:

$a = 10$
