Question 35 • (OC27) GEO-1206310-S2-Degele-VOL7006P

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.

Answer
A
8.2 cm
B
8.7 cm
C
22.6 m
D
25.5 cm

Explanation

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.
