Question

cosec thetha+cot theta=4 then what is sec theta​

Answer 1

Step-by-step explanation:

Let cosec theta-cot theta=x

We know cosec^2 theta-cot^2 theta =1

(cosec theta+cot theta)(cosec theta-cot theta)=1

cosec thea-cot theta=1/4

Using elimination method,

2cosec theta=17/4

cosec theta=17/8

sin theta=8/17

o/h=8/17

therefore a/h=cos theta=( √ (h^2-o^2))/h

=( √ 289-64)/17

= √ 225/17=15/17

therefore sec theta=17/15
