# Math Help - Geometry Question

1. ## Geometry Question

What I have is:
- The length of [AB]
- ABCD is a rectangle
- AFD is a right triangle
- Lines x and y are parallel
- Lines x and z are perpendicular

What I need to find is:
- The value of the angle ADE (a general formula for it)

You don't have enough information to get a general solution in terms of the variables you listed. Your angle could be anything between 0 and 90 degrees.

I agree with topsquark. We need more info. If you had the lengths of AE or AF as well, the problem could be solved. But maybe then it would be too easy and wouldn't be a problem.

5. ## New Problem

What I have is:
- The length of [AB]
- The length of [CG]
- The length between lines x and w
- ABCD is a rectangle
- DCGF is a rectangle
- AFD is a right triangle
- Lines x, y and w are parallel
- Lines x and z are perpendicular

What I need to find is:
- The value of the angle ADE (a general formula for it)

Can I get the value of angle ADE in this problem?

6. Someone check me on this, but I don't believe so.

Where are you getting these problems from?
