Question

solve for the value of d. answer attempt 1 out of 100 d =

Explanation:

Step1: Set up equation

Since the two angles are supplementary (sum to 180°), we have $(8d + 4)+(6d+8)=180$.

Step2: Combine like - terms

$8d+6d + 4 + 8=180$, which simplifies to $14d+12 = 180$.

Step3: Isolate the variable term

Subtract 12 from both sides: $14d=180 - 12$, so $14d=168$.

Step4: Solve for d

Divide both sides by 14: $d=\frac{168}{14}=12$.

Answer:

$12$
