Question

12tanA=5 then cosecA=?
​

Answer 1

Step-by-step explanation:

tan A = 5/12

P = 5 , B = 12

H^2 = 25 + 144

H = 13

cosec A= H/P

cosec A = 13/5

Answer 2

Answer:

❤️☺️HEY MATE ☺️❤️

HERE IS YOUR ANSWER ☺️ ☺️

tanA = 5/12 = P/B

=> P = 5x & B = 12x

we have,

H² = 25x² + 144x² = 169x²

H = 13x

cosecA = H/P = 13x/5x = 13/5.
