Question

If tan teta + Sec tetà=2/3.Then sec teta = ?

Answer 1

Step-by-step explanation:

HEY MATE ..

➞tan theta =2/3 - sec theta

➞tan2 theta = ( 2/3 - sec theta ) 2

: ( 1 + tan 2 theta =sec2 theta )

⇒sec2 theta - 1 = 4/9+ sec2theta - 4 sec theta /3

4 sec theta /3 =4/9 + 1 =13/9

⇒sec theta = 13/9 × 3/4 = 13/12

⇒sec theta = 13/12
