Question

what is the value of t?

Explanation:

Step1: Use the property of supplementary angles

Supplementary angles add up to \(180^{\circ}\).
So, \(t + 69^{\circ}=180^{\circ}\)

Step2: Solve for \(t\)

Subtract \(69^{\circ}\) from both sides of the equation:
\(t=180^{\circ}- 69^{\circ}\)
\(t = 111^{\circ}\)

Answer:

\(111\)
