In the figure, XYZ is a triangle with XY = 5cm, XZ = 2cm and XZ is produced to E making the angle < YZE = 150o. If the angle XYZ = \(\theta\), calculate the value of sin\(\theta\) A. \(\frac{3}{5}\) B. \(\frac{1}{2}\) C. \(\frac{2}{5}\) D. \(\frac{1}{5}\) Detailed Solution\(\frac{5}{\sin 36^o} = \frac{2}{\sin \theta} = \frac{5}{\frac{1}{2}} = \frac{2}{\sin \theta}\)10 = \(\frac{2}{\sin \theta}\) sin\(\theta\) = \(\frac{2}{10}\) = \(\frac{1}{5}\) |
