Question

tan inverse √3-sec inverse(-2) is equal to. a) 60, b) -60 , c)120 , d) -120 , e) none of this​

Answer 1

Answer:

option b -60° is correct

Step-by-step explanation:

tan⁻(√3) - sec⁻(-2) = tan⁻(√3) - cos⁻(-1/2)

                             = tan⁻(√3) - [180° - cos⁻(1/2)]

                             = 60° - [180° - 60°]

                             = -60°
