Explain in $2-3$ sentences why the slope below should be treated as a finite slope. Compute the factory of safety against sliding failure, if the slope angle is $40$ and the failure surface angle is $15$ measured from the horizonal. Perform the Factory of Safety computation twice: once using a stress approach and again using the force approach. Show how the factory of safety are the same when using the stress and force approach for a given slope angle and failure surface angle. Make a table to organize your results. Comment on the risk of failure for the slope. Comment on which shear strength parameters provide the most significant contribution for increasing the factor of safety.
