Question

solve for the value of d. (8d + 4)° (6d + 8)° answer attempt 1 out of 2 d =

Explanation:

Step1: Set up the equation

Since the two angles are complementary (sum to 90°), we have the equation $(8d + 4)+(6d + 8)=90$.

Step2: Combine like - terms

$8d+6d+4 + 8=90$, which simplifies to $14d+12 = 90$.

Step3: Isolate the variable term

Subtract 12 from both sides: $14d=90 - 12$, so $14d=78$.

Step4: Solve for d

Divide both sides by 14: $d=\frac{78}{14}=\frac{39}{7}\approx5.57$.

Answer:

$d=\frac{39}{7}$
