If sec(5A) = cosec(A-30) where 5A & (A-30) are acute angles , find the value of tan 3A. Share with your friends Share 0 Ritu Rajesh answered this 90-5A=A-30; 6A=120 ; A= 20 1 View Full Answer Ritu Rajesh answered this Now tan 3A= tan( 3?20)= tan 60= root 3 1 Safa answered this Thankyou :) 0 Shrava 😘😉 answered this A=20.tan 3A~tan60=?3 1 Harleen Kaur answered this Hope you understandd 1 Dharwish Shajid answered this sec(5A) = cosec (A-30) => cosec (90-5A) = cosec (A-30) Since they are acute angles, Therefore, 90-5A = A- 30 => 6A=120 => A=20 degrees 0
