If `0 lt theta lt pi//2 and 2 sin theta = sqrt(3) cos 10^(@) + sin 10^(@) , `then ` theta = `

0<=theta<(pi)/(2) and 2sin theta=sqrt(3)cos10^(@)+sin10^(@)

0 <theta <pi/2, 2sin theta = sqrt3 cos 10^@ + sin 10^@ => theta = (i) 50^0 (ii) 70^0 (iii) 40^0 (iv) 80^0

If : 0 lt theta lt pi/2 and sin 7theta + sin 4 theta + sin theta=0 , then : theta =

If 0 le theta lt pi/2 and costheta + sqrt(3) sin theta =2 , then what is the value of theta ?

If 0 lt theta lt pi/2 and sin 2 theta = cos 3 theta, then the value of sin theta is-

If sin theta = sqrt(3) cos theta, 0 lt theta lt 90^(@) , then theta is equal to .

If 0 lt theta lt pi/2 , the solution of the equation sin theta - 3 sin 2 theta + sin 3 theta = cos theta - 3 cos 2 theta + cos 3 theta is

If (cos theta +sin theta) : ( cos theta - sin theta) = (sqrt(3) +1): (sqrt(3)-1), 0^(@) lt theta lt 90^(@) , then what is the value of sec theta ?

If 2cos theta - sin theta = 1/sqrt(2), (0^(@) lt theta lt 90^(@)) then the value of 2sin theta + cos theta is:
