Explanation:

Step1: Recall the definition of supplementary angles

Supplementary angles add up to \(180^{\circ}\). Let the given angle be \(A = 145^{\circ}\) and its supplement be \(S\). Then the formula is \(A+S = 180^{\circ}\).

Step2: Solve for the supplement

We can rewrite the formula as \(S=180 - A\). Substitute \(A = 145\) into the formula: \(S=180 - 145\).

Answer:
