Question

what is the value of u? u+28 3u u =

Explanation:

Step1: Identify congruent segments

Since the perpendicular bisector $XZ$ divides the line segment $WY$ into two equal - length segments, we have $WZ = YZ$.
So, $u + 28=3u$.

Step2: Solve the equation for $u$

Subtract $u$ from both sides of the equation:
$u+28 - u=3u - u$.
This simplifies to $28 = 2u$.
Then divide both sides by 2: $\frac{28}{2}=\frac{2u}{2}$.

Answer:

$u = 14$
