• A. $94°$
• B. $84°$
• C. $176°$
• D. $86°$

Answer: (C)

Verified step by step guidance

1. Recall that two angles are supplementary if the sum of their measures is 180 degrees.
2. Let the given angle be represented as \(4^\circ\) and the supplementary angle as \(x^\circ\).
3. Set up the equation for supplementary angles: \(4^\circ + x^\circ = 180^\circ\).
4. Solve for \(x\) by subtracting 4 degrees from both sides: \(x = 180^\circ - 4^\circ\).
5. Calculate the value of \(x\) to find the measure of the supplementary angle.
