Question

what is the value of j? 115° j

Explanation:

Step1: Recall angle - sum property

The two angles are supplementary, meaning their sum is 180°. Let the given angle be 115° and the unknown angle be \(j\). So, \(115^{\circ}+j = 180^{\circ}\).

Step2: Solve for \(j\)

Subtract 115° from both sides of the equation: \(j=180^{\circ}- 115^{\circ}\).

Answer:

65
