Question

Pls solve the above question​

Answer 1

$\huge\mathcal\purple{\boxed{\boxed{Solution}}}$

${2sin^2\theta}$${=}\large\frac{3}{2}$

${sin^2\theta}$${=}\large\frac{3}{4}$

${sin\theta=}$$\sqrt\frac{3}{4}$

${sin\theta=}$√3/2

${sin\theta=sin60\degree}$

${\theta=60\degree}$

Answer 2

Solution :-

2sin²∅ = 3/2

= sin²∅ = 3/4

= sin∅ = √3/√4

= sin∅ = √3/2

= sin∅ = sin60°

= ∅ = 60°
