A rectangular TV screen measures 36 inches wide and 27 inches tall. What is the diagonal screen size?
A 40 inches
B 45 inches
C 50 inches
D 63 inches
Explanation
📌 Step 1: Apply the Pythagorean Theorem
d² = 36² + 27²
d² = 1296 + 729
d² = 2025
📌 Step 2: Solve
d = √2025 = 45 inches
💡 Tip: 27-36-45 is a multiple of the 3-4-5 triple (×9). Recognizing this pattern: 27/9=3, 36/9=4, so d/9=5, d=45.
