QS = 20.7

Explanation:

To get length of side QS, we will consider triangle SQR (right angle triangle)

opposite (the side opposite the angle 28°) = QS

adjacent = base = 39

We apply tangent ratio:

tan28 = opposite/adjacent

tan28 = QS/39

QS = 39 × tan28

QS = 39 × 0.5317

QS = 20.7363

To the nearest tenth, QS = 20.7
