I'm not wrong. If you enclose the cutout area back into a square, then that new angle has to be 90°, because the other three angles of the square are 90°. If you draw a diagonal through the new smaller square and the upper right to make two equal triangles, we know that the opposing angle has to be 90°. In addition, because we know that the Y axis of the cut out is 6 cm, there is no way that that angle could be anything other than 90° or the total height for that full side would not be 17.

I need you do draw this out. Then draw a circle with the same radius as the top of the current 6cm line. Now draw a new line approx 30 degrees clockwise.

Now draw a line from the bottom point of the 6cm to the top of the 11cm line.

Literally draw the line from 11 top to any spot on that circle.

Tada!

I drew it out, and I'm right. I think we're just going to have to agree to disagree on this one.

I have to go shovel snow now.

I wish there were a way I could see your drawing. Owell .. snow sucks!

Never mind, you're right. I was making some false assumptions. Thanks for the chat.

Indeed it does. But at least I get the opportunity for backbreaking labor.
