If $3sec^2 x - 4 = 0 $, then the value of x ( 0 < x < 90°)
Answer & explanation
Correct answer: option 3
3 sec²x - 4 = 0
3 sec²x = 4
secx = \(\frac{2 }{√3}\)
{ we know, sec30º = \(\frac{2 }{√3}\) }
So,
x = 30º
If $3sec^2 x - 4 = 0 $, then the value of x ( 0 < x < 90°)
Correct answer: option 3
3 sec²x - 4 = 0
3 sec²x = 4
secx = \(\frac{2 }{√3}\)
{ we know, sec30º = \(\frac{2 }{√3}\) }
So,
x = 30º
