Question

1. find the length indicated. *hint, writing an equation is helpful. r 12 w p q 15 w =

Explanation:

Step1: Identify the relationship

From the figure, we know that the length from $R$ to $P$ is composed of the length from $R$ to $Q$ and the length from $Q$ to $P$. So $12 + w=15$.

Step2: Solve for $w$

Subtract 12 from both sides of the equation: $w = 15 - 12$.

Answer:

$3$
