So

We know the ratio

  • x:y:z=30:60:90=1:√3:2

Now

x=2

So

  • 2:y=1:√3
  • y=2√3

And

  • 2:z=1/2
  • z=4

Option A

Answer:

  • A) 2√3

Explanation:

Side ratios of 30°-60°-90° triangle:

  • a : b : c = 1 : √3 : 2

Given:

  • a = 2

Find b:

  • 2 : b = 1 : √3
  • b = 2*√3/1
  • b = 2√3

Correct choice is A
