A direct shear test is performed on a soil sample with two different loads. In the first test, a normal stress of 55kPa is applied and the soil fails at a shear stress of 35kPa. In the second test, the soil failed at shear stress of 47kPa when a normal stress of 75 kPa was applied. Determine the values of internal friction angle and cohesion of the given soil sample.
