\sin 32^{\circ}=k

and

\cos x=1-2 k^2 ; \alpha, \beta

are the values of

x

between

0^{\circ}

and

360^{\circ}

with

\alpha < \beta

, then

View answer and explanation

Correct option: C

\beta=4 \alpha+40^{\circ}

Option C (

\beta=4 \alpha+40^{\circ}

) is correct because by solving for x and substituting the values of alpha and beta, the equation holds true.
