To find the length of the diagonal of the mirror, you can use the Pythagorean theorem. Given the two sides of the mirror (38 inches and 30 inches), you would calculate it like this:
Diagonal (d) = √(38² + 30²) = √(1444 + 900) = √2344. This gives you approximately 48.4 inches. When rounded to the nearest inch, the answer is 48 inches.
Have you ever wondered how mirrors have evolved over time? From the first polished metal surfaces used in ancient Egypt to the reflective glass we enjoy today, mirrors have been fascinating tools for both functionality and art in our lives!
Today, mirrors are not just for checking appearances; they’re widely applied in technology, such as in cameras, telescopes, and even solar energy systems, reflecting light to harness energy!
