Question

what is the value of u?
$u = \square$
submit

Explanation:

Step1: Identify congruent segments

Since $G$ is equidistant from $H$ and $F$ (marked congruent sides), the line $GE$ is the perpendicular bisector of $HF$. Thus, $HE = EF$.

Step2: Set up equation for equality

$3u = u + 34$

Step3: Solve for $u$

Subtract $u$ from both sides:
$3u - u = 34$
$2u = 34$
Divide by 2:
$u = \frac{34}{2}$

Answer:

$17$
