A man with a mass equal to 70 kg crosses a rope bridge over a river, as shown in the figure. The angles that the rope makes with a horizontal line, at the position where the man is, are equal to 15° and 25°. What are the tension forces acting on the rope?
Data: cos 15° = 0.9659, sin 15° = 0.2419, cos 25° = 0.9063, sin 25° = 0.4226.
