solve for the value of $k$.

Explanation:

Step1: Set up the equation

Since the two angles form a right angle (90°), we have \(73+(9k + 8)=90\).

Step2: Simplify the left - hand side

Combine like terms: \(9k+81 = 90\).

Step3: Isolate the term with \(k\)

Subtract 81 from both sides: \(9k=90 - 81\), so \(9k = 9\).

Step4: Solve for \(k\)

Divide both sides by 9: \(k=\frac{9}{9}\).

Answer:

\(k = 1\)
