Question

what is the supplement of 40°? s = ?°

Explanation:

Step1: Recall the definition of supplementary angles

Supplementary angles add up to \(180^{\circ}\).

Step2: Set up the equation

Let the supplement of \(40^{\circ}\) be \(S\). Then \(S + 40^{\circ}=180^{\circ}\).

Step3: Solve for \(S\)

Subtract \(40^{\circ}\) from both sides: \(S=180^{\circ}- 40^{\circ}\).
$$S = 140^{\circ}$$

Answer:

\(140\)
