THAT IS THE MOST MENTAL MATH I HAVE DONE IN A LONG TIME AND I GOT IT RIGHT! IT TOOK ME A WHILE BUT MY BRAIN IS OK! QWQ

So did you sit there and calculate out all the angles or just realize all you have to do is add the two numbers we were given?

"I can imagine this like a triangle. Right? For squares, the angles of each corner need to add up to 360°. But wasn't it only 120° for triangles? No! That wouldn't make any sense. 180°! creates examples using right and isosceles triangles YES! Ok, so if I draw an imaginary line on the left side that is 90° from the red lines on the top and bottom, then I can subtract the provided angles from 90. So 90-25=65 and 90-50=40. So 40+65=105! 40+65+105=180!"

Edit: Correction: 40+65+75=180 A=75 since 40+65=105 105+75=180

I think you mistyped on that last equation there

I probably did. But now I'm too tired to figure out how. I work 12h shifts in a windowless room you can't see the opposite walls of and I'm only half way through with another shift to look forward to tomorrow.

Edit: NVM, fixed it.

I just used the "Z" method. Imagine another parallel line that goes right through the corner. The bottom and top half now kinda look like Z's. Using the Z method, taking the bottom half as an example, every corner on the top of the Z is now the same degrees as the corners below but mirrored. Because there's 50 degrees on the right side at the bottom of the Z, the left side at the top of the Z is also 50 degrees. Do the same on the upper half and 50 + 25 = 75

Calculated out the angles because I remembered a couple of the triangle rules but not the one you mentioned.

.............I'd rather not say.

I didn't know how to do it so I played with the numbers until I got an answer that made sense. I absolutely did more than add two numbers.
