Question #f8838 Trigonometry Right Triangles Trigonometric Functions of Any Angle 1 Answer P dilip_k Feb 23, 2017 Since #sinx =2/3->+ve and cosx <0->-ve# the angle x should be II quadrant So #cosx=-sqrt(1-sin^2x)=-sqrt(1-4/9)=-sqrt5/3# #secx=1/cosx=-3/sqrt5# #cscx =1/sinx=3/2# #tanx=sinx/cosx=(2/3)/(-sqrt5/3)=-2/sqrt5# #cotx=1/tanx=-sqrt5/2# Answer link Related questions How do you find the trigonometric functions of any angle?
