Question

what is the value of j? 105.3° j

Explanation:

Step1: Recall angle - sum property

The two angles are supplementary, so their sum is $180^{\circ}$.

Step2: Set up the equation

Let the unknown angle be $j$. We have $j + 105.3^{\circ}=180^{\circ}$.

Step3: Solve for $j$

$j=180^{\circ}- 105.3^{\circ}=74.7^{\circ}$

Answer:

$74.7$
