sec A = 25/7 = H/B
let H = 25k
B = 7k
Now,
By using Pythagoras Theorm
H² = B² + P²
⇒ (25k)² = (7k)² + P²
⇒ 625k² = 49k² + P²
⇒ 625k² - 49k² = P²
⇒ 576k² = P²
⇒ (24k)² = P²
∴ P = 24k
Tan A = P/B = 24k/7k
k got cancelled from both the sides so we get 24/7
Cosec A = H/P = 25k/24k
k got cancelled from both the sides so we get 25/24
