Answer:

XY=8.2 cm

Explanation:

The attached figure shows a triangle XYZ. It is right angle at vertex Y and XZ = 24 cm. Also, angle ZXY = 70°

We need to find the length of line segment XY. It can be calculated using Trigonometry. So,


\cos\theta=(B)/(H)\\\\\cos(70)=(XY)/(24)\\\\XY=\cos(70)* 24\\\\XY=8.2\ cm

So, the length of the line segment XY is 8.2 cm. Hence, the correct option is (a) "8.2 cm".
