Question

If tan x =15/12, then find sec x.​

Answer 1

Answer:

13/12

Step-by-step explanation:

according to Pythagorean theorem hyp=13

find cosx=12/13

therefore secx=13/12

Answer 2

Answer:

sec^2X=tan^2x +1

sec^2x=(15/12)^2 +1

=225/144 + 1

sec X =15/12 + 1

15 + 12/12

=27/12 = 9/4

hence, sec X = 9/4.
