(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Given that 5sec^2+3tan^2 = 9

find sinx value

2. Relevant equations

trig. identities

3. The attempt at a solution

i started off by subbing. in sec2= 1+tan^2

=>

5(1+tan^2)+3tan^2= 9

5+8tan^2x = 9

8tan^2 = 4

tan^2 = 1/2 <--- no idea of this bit, as i am supposed to find sin x value =/ , hmm i even wonder if this right.
