Question

what is the value of j? 139.1° j

Explanation:

Step1: Use the property of supplementary angles

Supplementary angles add up to \(180^{\circ}\). Let the angle \(j\) and \(139.1^{\circ}\) be supplementary.
So, \(j + 139.1^{\circ}=180^{\circ}\)

Step2: Solve for \(j\)

Subtract \(139.1^{\circ}\) from both sides of the equation.
\(j=180^{\circ}- 139.1^{\circ}\)
\(j = 40.9^{\circ}\)

Answer:

\(40.9\)
