Hey guys,
I'm stumped on these two problems, and was wondering if someone could shed some light on them for me.
1. Parallelogram ABCD has vertices at A(-1, x - 1), B(x, x + 1), C(3, 1), and D(x - 2, -1). Use the slopes of AB and CD to find "x".
I came up with these answers:
Slope of AB = 0
Slope of CD = -2/x - 5
So now I can't figure out what to do. How am I supposed to find "x" with these answers? Did I do something wrong?
2. According to the Americans With Disabilities Act, a ramp is a route with a slope greater than 1/20. The maximum allowable slope of a ramp is 1/12, and the maximum rise is 30 in. What are the minimum and maximum runs for a ramp with a rise of 30 in.?
I honestly can not figure out what to do...period. Any help, or advice would be awesome! I really appreciate it!
Thanks.
