Question 3 The Americans with Disabilities Act states that ramps must have an angle less than equal to 4.8 degrees. Remember, a 4.8 degree angle in a right triangle has a \( 1: 12 \) ratio for the legs. Select all designs of a ramp that meet the Americans with Disabilities Act requirements. \[ \begin{array}{ll}\square & \text { A) Right triangle with legs } 3 \text { meter and } 33 \text { meter. } \\ \square & \text { B) Right triangle with legs triangle with legs } 12 \text { meter and } 12 \text { meters. } \\ \square & \text { D) Right triangle with legs } 12 \text { feet and } 150 \text { feet. } \\ \square & \text { E) Right triangle with legs } 24 \text { units and } 240 \text { units. } \\ \square\end{array} \]

Did you know that the Americans with Disabilities Act (ADA) was signed into law in 1990 to ensure equal rights and accessibility for individuals with disabilities? It was a monumental step towards inclusivity, leading to changes in public buildings, transportation, and even employment policies. The ADA has paved the way for better accessibility features like ramps, elevators, and accessible restrooms, enabling people to navigate spaces that were previously difficult or impossible to access. When designing a ramp, always remember the slope ratio of 1:12. This means for every inch of vertical rise, there should be at least 12 inches of horizontal run. Common mistakes include making ramps too steep or exceeding the height limit for safe access. Picture this: a ramp built at a 1:10 ratio might seem functional, but it can lead to a challenging experience for users, especially those in wheelchairs. Always take your time to calculate and measure both the rise and run accurately!
