If 8 cos x − 15 sin x = r cos(x + α), find the values of r and α, r being a positive number and α an angle between 0◦ and 360◦ . 23. If tan θ = k tan(α − θ), prove that k−1 sin(2θ − α) = . k+1 sin α Find all the angles between 0◦ and 360◦ , which satisfy the equation tan θ = 3 tan(150◦ − θ). 1 24. If tan α = −2, where 0 < α < π , and tan β = , where π < β < 2π , find α + β without using 3 tables or a calculator. 2...
