Question

Find the length of side o in simplest radical form with a rational denominator

Answer 1

4.5

Explanation:

Answer 2

• x = 4.5 units

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
