Cassandra assigns values to some of the measures of triangle [tex]\( ABC \)[/tex]. If angle [tex]\( A \)[/tex] measures [tex]\( 30^{\circ} \)[/tex], [tex]\( a = 6 \)[/tex], and [tex]\( b = 18 \)[/tex], which is true?

A. The triangle does not exist because [tex]\(\frac{\sin A}{a}\)[/tex] cannot equal [tex]\(\frac{\sin B}{b}\)[/tex].

B. The triangle is a right triangle because [tex]\(30^{\circ}\)[/tex] times 3 is [tex]\(90^{\circ}\)[/tex], and 6 times 3 is 18.

C. There is one non-right triangle that can be created with those measures because [tex]\( a \ \textless \ b \)[/tex].

D. There are two non-right triangles that can be created with those measures because [tex]\( a \ \textless \ b \ \textless \ A \)[/tex].



Answer :

Let's carefully analyze the given situation to determine which condition is true for the triangle with the given values.

We have:
- Angle A = [tex]\(30^\circ\)[/tex]
- Side [tex]\(a = 6\)[/tex]
- Side [tex]\(b = 18\)[/tex]

To determine the correct statement about this triangle, let’s use the properties and relationships in geometry, specifically focusing on the angle-side relationships.

1. Angle and Side Relationships:

Given that [tex]\(\angle A = 30^\circ\)[/tex], we should verify the relationship with sides using the Sine Rule, which states:
[tex]\[\frac{\sin A}{a} = \frac{\sin B}{b}\][/tex]

- We know [tex]\(\sin(30^\circ) = \frac{1}{2}\)[/tex].

Then:
[tex]\[ \frac{\sin 30^\circ}{6} = \frac{\frac{1}{2}}{6} = \frac{1}{12} \][/tex]
Similarly, for the other side:
[tex]\[ \frac{\sin B}{18} = \frac{1}{12} \][/tex]

From these equations, it is evident that [tex]\(\sin B\)[/tex] for side [tex]\(b = 18\)[/tex] must satisfy:
[tex]\[ \frac{\sin B}{18} = \frac{1}{12} \implies \sin B = \frac{18}{12} = 1.5 \][/tex]

However, [tex]\(\sin B\)[/tex] cannot be greater than 1 for any angle [tex]\(B\)[/tex] in a non-hypothetical context. Therefore, as long as Angle A equals [tex]\(30^\circ\)[/tex], and the sides are related in the ratio given, we should identify the key relationships for the stated conditions.

2. Specific Triangular Conditions:

- Right Triangle:
The second possible choice is that the triangle is right because [tex]\(30^\circ\)[/tex] is involved.

Let's see if we could use another approach:

[tex]\( \frac{\sin 30^\circ}{6} \equates to \frac{1}{2}/6 = \frac{1}{12} = \sin B \)[/tex]. For [tex]\(a=6, b = 18\)[/tex], we see in trigonometric construction having same angles in respect to another known proportional comparative.

This equates to satisfying angle properties: [tex]\(30^{\circ}\times 3 = 90^{\circ}\)[/tex], multiplying any proportional length [tex]\(6\times 3 = 18\)[/tex]. Essentially signifies an alignment with conditions enumerated: \[
Angle = 90, Length conversion ×3 Ratio
]

Thus, considering all geometrical properties and careful reanalysis, Given angle A measures and specificity with side:

- The valid conclusive end statement proclaims:
```Correct answer which substantiates:

\( "The triangle is a right triangle because 30°×3 =90°, and 6×3 =18. \")
