Question

what is the value of j? 78.2° 28.6°

Explanation:

Step1: Identify the angle relationship

The total angle (78.2°) is the sum of \( j \) and 28.6°. So we can write the equation \( j + 28.6^\circ = 78.2^\circ \).

Step2: Solve for \( j \)

Subtract 28.6° from both sides of the equation: \( j = 78.2^\circ - 28.6^\circ \).
Calculate the right - hand side: \( 78.2 - 28.6 = 49.6 \). So \( j = 49.6^\circ \).

Answer:

\( 49.6^\circ \)
