Right triangle XYZ has a right angle at vertex Y and a hypotenuse that measures 24 cm. Angle ZXY measures 70o.What is the length of line segment XY? Round to the nearest tenth.

Since the hypotenuse is 24 cm and XY is adjacent to the 70° angle, use cosine: cos(70°) = XY / 24. Thus XY = 24 cos(70°) ≈ 8.2 cm when rounded to the nearest tenth. The correct choice is 8.2 cm.
