Suppose that the terminal side of angle α lies in Quadrant II and the terminal side of angle β fies in Quadrant I. If tan α=−158 and cos β=85, find the axact vatue of cos(α−β) cos(α−1)= (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression. Do not factor.)
