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
