Select the correct answer.

The shortest side of a right triangle measures [tex]\(3 \sqrt{3}\)[/tex] inches. One angle of the triangle measures [tex]\(60^{\circ}\)[/tex]. What is the length, in inches, of the hypotenuse of the triangle?

A. 3
B. [tex]\(6 \sqrt{2}\)[/tex]
C. [tex]\(6 \sqrt{3}\)[/tex]
D. 6



Answer :

To determine the length of the hypotenuse of the given right triangle, we start with the given information:

1. The shortest side of the right triangle is [tex]\( 3 \sqrt{3} \)[/tex] inches.
2. The triangle has an angle of [tex]\( 60^{\circ} \)[/tex].

Given these facts, it's useful to recognize that we are dealing with a 30-60-90 triangle. In a 30-60-90 triangle, the sides have fixed ratios:
- The side across from the [tex]\( 30^{\circ} \)[/tex] angle is the shortest side and can be denoted as [tex]\(x\)[/tex].
- The side across from the [tex]\( 60^{\circ} \)[/tex] angle is [tex]\(x \sqrt{3}\)[/tex].
- The hypotenuse (across from the right angle) is [tex]\(2x\)[/tex].

Here, the shortest side (across from the [tex]\(30^{\circ}\)[/tex]) is given as [tex]\( 3 \sqrt{3} \)[/tex]. Based on the properties of a 30-60-90 triangle:
- Let's denote the shortest side as [tex]\(x\)[/tex]. Thus, [tex]\( x = 3 \sqrt{3} \)[/tex].
- The hypotenuse is [tex]\(2x\)[/tex].

So, let's calculate the hypotenuse:
[tex]\[ \text{Hypotenuse} = 2 \times 3 \sqrt{3} = 6 \sqrt{3} \][/tex]

Now we compare this value with the given multiple-choice options:
A. 3
B. [tex]\( 6 \sqrt{2} \)[/tex]
C. [tex]\( 6 \sqrt{3} \)[/tex]
D. 6

The correct answer, based on our calculation, matches option C:
[tex]\[ \boxed{6 \sqrt{3}} \][/tex]
