The Americans with Disabilities Act states that

to 4.8 degrees. Remember, a 4.8 degree angle
in a right triangle has a 1 : 12 ratio for the
legs. Select all ramps that meet the Americans
with Disabilities Act requirements.

Answer 1

A,C,D

Explanation:

requirement is an angle less than or equal to 4.8 degrees. which means 1:12 or less

1:15 is OK.

the one with 15 and 2, missing the leg - you can calculate by 15²-2² = 221

√221 = 14.87

2:14.87 is bigger than 1:12, so no go.
