Help needed figuring out angles to cut wood for chicken ark pen

[jimmywalt]

I want to build a 4' x 8' chicken ark pen. I'm trying to figure out what angles I need to cut the ends of the boards at A, B & C so that this all fits together properly. The 3' boards will go inside of the rectangular frame at the base, and there will be a 8' board at the top going the length.

So I need to figure out what the angle cuts are for A, B & C.

I have a miter saw, table saw and circular saw.

If you can help me that would be great. Thank you!

Oops!

That was wrong.

I can tell you that angle A > 60º <90º

I can tell you B = C > 45º

Angle A+ B + C = 180º

Otherwise I would tack your frame together and scribe your angles then cut to fit.

I do not have the math or geometry skills to help you out buddy.

You might draw it to scale on paper or full size on the dirt and measure your angles.

Angle A is 84 degrees
Angles B and C are 48 degrees

Angle A is 84 degrees
Angles B and C are 48 degrees

Correct

*I* 'cheated' because I drew it up in cad with the measurements given and then measured the angles.

Thanks everyone. I plan to build tomorrow.
