Solve for y
A) 6
B) 6 sqrt 3
C) 4
D) 4 sqrt 3

Answer:
A) 6
Step-by-step explanation:
in a 30-60-90° Δ the ratio of side lengths is 1 : [tex]\sqrt{3}[/tex] : 2
so we can set up this proportion and cross-multiply:
[tex]\sqrt{3}[/tex] / 1 = y / 2[tex]\sqrt{3}[/tex]
y = 2[tex]\sqrt{3}[/tex][tex]\sqrt{3}[/tex] which is 2x3 or 6
