Question 10 (Multiple Choice Worth 1 points)
(05.01 MC)
In $\triangle P Q R$, what is the length of segment $Q R$ ?
Solution
Solution Steps
Step 1: Identify the given information
Length of segment GE = \( 97\sqrt{3} \) units
Length of segment BG = 149 units
We need to find the length of segment AC
Step 2: Analyze the triangle properties
The triangle has angles of 45°, 60°, and 90°, indicating it is a right triangle.
Segment GE is opposite the 60° angle, making it the longer leg in a 30°-60°-90° triangle.
Step 3: Use the properties of a 30°-60°-90° triangle
In a 30°-60°-90° triangle, the ratio of the sides opposite the 30°, 60°, and 90° angles are \( 1 : \sqrt{3} : 2 \).
Given GE = \( 97\sqrt{3} \), which is opposite the 60° angle, the hypotenuse (opposite the 90° angle) is \( 2 \times 97\sqrt{3} / \sqrt{3} = 2 \times 97 = 194 \) units.
