Answer:
6✓3
Step-by-step explanation:
consider a triangle RST
Given that,
RST angle =90degree
then we say that it's a right angled triangle
So it has three sides opp,hyp,and adj
Let Rs is opposite side,ST is adjacent
and RT is hypotenuse
RT=12 cm (given)T=30degree
then,
cos 30=adj/hyp
√3/2=ST/12
ST=12×√3/2
ST=6√3
