Question

1. find d if $overline{ab}congoverline{bc}$. 10 5d - 2 a b c

Explanation:

Step1: Set up the equation

Since $\overline{AB}\cong\overline{BC}$, we set $10 = 5d - 2$.

Step2: Add 2 to both sides

$10+2=5d - 2+2$, which simplifies to $12 = 5d$.

Step3: Solve for d

Divide both sides by 5: $d=\frac{12}{5}=2.4$.

Answer:

$d = 2.4$
