Question

write the algebraic expression described. recall that two angles are supplementary if their sum is 180°. if one angle measures u°, express the measure of its supplement in terms of u°. the measure of its supplement in terms of u° is (□)°.

Explanation:

Step1: Recall supplement - angle relationship

Let the measure of the supplement be \(x\). We know that \(u + x=180\).

Step2: Solve for \(x\)

Subtract \(u\) from both sides of the equation \(u + x = 180\). So \(x=180 - u\).

Answer:

\(180 - u\)
