$0-2$ A block is at rest on an inclined plane whose elevation can be varied. The coefficient of static friction is ${}_s=0\mathrm{.}25,$ and the coefficient of kinetic friction is ${}_k=0\mathrm{.}19.$ The angle of elevation $$ of the inclined plane is increased slowly from the horizontal. At what value of $$ does the block begin to slide?
