Question

if sec 5a=cosec (a+36°)and 5a is a positive acute angle;let you find the value of a

Answer 1

sec90-theta=cosec theta
therefore..5a=90-theta
and. a+36=theta.
let me suppose theta be X
then,90-5a=x
a+36=x
then...90-5a=a+36
54=6a
then ,a=54/6=9

Answer 2

Answer:9

Step-by-step explanation:

sec90-theta=cosec theta

therefore..5a=90-theta

and. a+36=theta.

let me suppose theta be X

then,90-5a=x

a+36=x

then...90-5a=a+36

54=6a

then ,a=54/6=9
