Question

what is the value of u? 130.8° u

Explanation:

Step1: Identify angle - relationship

The two angles are supplementary (a straight - line forms 180°).

Step2: Set up the equation

Let the given angle be 130.8°. We know that \(u + 130.8^{\circ}=180^{\circ}\).

Step3: Solve for \(u\)

\(u=180^{\circ}- 130.8^{\circ}\).
\(u = 49.2^{\circ}\)

Answer:

\(49.2\)
