hey correct ur answer yar
its correct
1/4+2 u shld take lcm yar
kk thnx
wlcm
i frgt to do LCM
its ok yar
chance co30 degree into s 1/sin30 degree
then solve this
cosec 30 degree = 1/sin30 degree

SIn 30 = 1/2
Cos 60 = 1/2
Cosec 30 = 1/sin30
=1/1/2
=2
So substituting these values:
1/2 * 1/2 + 2
=1/4 + 2
=9/4
Cos 60 = 1/2
Cosec 30 = 1/sin30
=1/1/2
=2
So substituting these values:
1/2 * 1/2 + 2
=1/4 + 2
=9/4
pls mark as best if i helped
