Answer:

  • x = 4.5 units

Step-by-step explanation:

Given is the 30*60*90 right triangle.

Its side ratio is:

  • a : b : c = 1 : √3 : 2, from the shortest to the longest sides

We have:

  • c = 9
  • a = x

Use the above ratios to find the length of a:

  • a : c = 1 : 2
  • x : 9 = 1 : 2
  • x = 9/2
  • x = 4.5
