Question

If tanA = 12/5, find the value of SecA.

Answer 1

sec²A = 1 + tan²A = 1 + 12²/5²

= 1 + 144/25 = 169/25

secA = 13/5.

Answer 2

hello friend____☺

solution:-

we know that

sec^2A = 1+ tan^2A

put value of tan A= 12/5, we get,

= 1+ (12/5)^2

= 1+ 144/25

= 1+ 5.76

= 6.76

thank you___☺
