You're building a 12 foot ramp to the entrance of a building 3 feet above the ground. The ADA regulations require the incline of the ramp to be no more than 5 degrees. What is the degree measure of your angle of elevation? Will it fit the requirements? If not, can you think of a way to make it work. Never mind.

In a right-angled triangle: 1- the hypotenuse is the longest side2- we can apply pythagorean rule which states that: (hypotenuse)^2 = (side1)^2 + (side2)^2for the given triangle,longest side is 15 cm  side1 = 9 cmside2 is 12 cm  to check whether the triangle is right-angled or not,compare (15)^2 to the summation of (9)^2 and (12)^in other words, compare 225 to the summation of 81 and 144if they are both equal, then the triangle is right-angles, otherwise, it is not.you haven't provided the diagram showing her work, so i cannot tell the choice. however, apply my explanation to the question you have.
