Not enough information.
You need to know the other two angles. Then you can use trig to determine the total length of the sides, and from there you can determine the sides of the square.
You don't need any more info. You don't care what the actual angles are, you just know that they're the same. Take the tangent of each because you know the opposite and adjacent sides, solve for x.

My wife is an engineer, so yes.
I am not an engineer, so no.

Not enough information. You can solve it if you knew for certain that it was a right triangle AND that the area containing the "?" was a square.

350?

True, but if all of those are assumed:

The problem doesn't say it's a 30-60 or 45-45 right triangle and you can't assume.
How does stupidity like this get upvotes, especially this late in the thread?

Hi about square root of 3x12.
How about 30-60-90 the short sides 1/2 the long side. Shouldn’t need a pencil.

That one is not nearly as easy as the OP one

The word square is right in the question, which also means it must be a right triangle.

You would have to assume the square and triangle is actually square and that was not a given.

This is so retarded.
None of y’all’s mommas could solve this, but y’all did. QED.

It’s a right triangle and assuming it’s a 3-4-5 right triangle
5 + x = 3/4(20+x)
5 + x = 15 + 3/4x
5 + 1/4x = 15
1/4x = 10
X = 40
Check:
The two sides are 45 and 60
45 = 3/4 (60)
So if X = 40
The area is 1600 square inches
Oh lawd.
You assumed (incorrectly) that it's a 3-4-5 triangle for no reason whatsoever. Then the only thing your "check" checked was that you forced the numbers into your 3-4-5 assumption.
If you construct the shape per your dimensions, starting with a 40x40 square, then continue the right side up another 20, and the bottom to the left another 5, then connect the ends of those lines to the top left corner of your square, you will see that you have not even drawn a triangle.

My wife can solve it but she does have a BS in mathematics

First one is 100. Second one is 625.
My wife guessed 80.
My kids are smarter than average but geometry is not her thing.

Naught, naught, double naught naught is correct. I cipher good.
