If \( RS = 39.3 \) and \( QS = 54.4 \), find \( QR \).

A. \( QR = 93.7 \)
B. \( QR = 15.1 \)
C. \( QR = 93.7 \)
D. \( QR = 6.9 \)

Answer :

Final answer:

The length of the side QR of the triangle can be determined by applying the triangle inequality theorem. By subtracting the length of RS from QS, we arrive at 15.1. Thus, option B is correct

Explanation:

The question gives two sides of a triangle: RS (39.3 units) and QS (54.4 units). To find the length of side QR, we infer that this might be a question relating to the triangle inequality theorem, which states that the length of one side of a triangle is always lesser as compared to the sum of the lengths of the other two sides.

To calculate QR, we deduct the length of RS from QS. That is why QR = QS - RS. Substituting the given values gives QR = 54.4 - 39.3, which means QR = 15.1. Therefore, the correct option is B. QR = 15.1.
