If 2 sin 2θ = `sqrt(3)` then the value of θ is
पर्याय
90°
30°
45°
60°
उत्तर
30°
Explanation;
Hint:
2 sin 2θ = `sqrt(3)`
⇒ sin 2θ = `sqrt(3)/2`
sin 2θ = sin 60°
⇒ 2θ = 60°
θ = 30°

Given A = 60° and B = 30°,
prove that : sin (A + B) = sin A cos B + cos A sin B
If tan (A + B) = 1 and tan(A-B)`=1/sqrt3` , 0° < A + B < 90°, A > B, then find the values of A and B.
If sin x = cos y; write the relation between x and y, if both the angles x and y are acute.
If A = 30o, then prove that :
2 cos2 A - 1 = 1 - 2 sin2A
If A = 30° and B = 60°, verify that: `(sin("A" -"B"))/(sin"A" . sin"B")` = cotB - cotA
If A = B = 45°, verify that sin (A - B) = sin A .cos B - cos A.sin B
