Solution :-

7sin θ - 24cos θ = 0

→ 7sin θ = 24cos θ

→ sin θ/cos θ = 24/7

using :-

  • sin A / cos A = tan A in LHS,

→ tan θ = 24/7

using :-

  • sec² A - tan² A = 1

→ sec² θ - (24/7)² = 1

→ sec² θ - (576/49) = 1

→ sec² θ = 1 + (576/49)

→ sec² θ = (49 + 576)/49

→ sec² θ = (625/49)

→ sec² θ = (25/7)²

square root both sides now,

→ sec θ = 25/7 (Ans.)
