They are testing whether you remember the basic 30,60,90 degree triangle side relationship. The ratio of sides for this triangle are 1 opposite the 30 degree angle, square root of three opposite the 60 degree angle and a hypotenuse of 2 opposite the 90 degree angle.
x/2=2/1
x=4/1=4
bottom answer choice

If she already has 5, she would need to buy 27 more bracelets to have 32. So she would need to buy 8 packs of bracelets to give all her friends bracelets.
% is 1/100 part of whole
so 1% is 200/100=2
and 8% is 2*8=16
or
200/100*8=2*8=16
or
200*0.8=16
Answer: 16
