Question

solve for the value of a. 104° (8a - 4)° answer attempt 2 out of 2 a =

Explanation:

Step1: Set up equation

Since the two angles are vertical - angles and vertical - angles are equal, we set up the equation $8a - 4=104$.

Step2: Add 4 to both sides

$8a-4 + 4=104 + 4$, which simplifies to $8a=108$.

Step3: Divide both sides by 8

$a=\frac{108}{8}=\frac{27}{2}=13.5$.

Answer:

$13.5$
