Hello,
When you have a polygon inscribed in a circle, the opposite angles are supplementary.
So we can start by saying that A + C = 180. Or x + 3x = 180. This gives us a value of 45 for x.
If we input that in for angle B, we get: 2(25) - 10 = 80.
If angle B = 80, then angle D must be 100, because the angles are supplementary.
Good luck,

Well the question says "rewrite each statement using symbols so I guess it means using symbols...
31x^2 + 53x - 8
Use the FOIL method to find the area of the large rectangle. (7x - 2)(9 + 5x)
First term in each binomial: 7x * 9 = 63x
Outside terms: 7x * 5x = 35x^2
Inside terms: -2 * 9 = -18
Last term in each binomial: -2 * 5x = -10x
Now, just add them all up.
63x + 35x^2 - 8 - 10x
35x^2 + 53x - 8
Now find the area of the square.
2x * 2x = 4x^2
Now, subtract the areas.
31x^2 + 53x - 8

3/5 are not polka dotted, so first find 1/5. 20/5 is 4, so 1/5=4. 4x3 is 12 ribbons. Hope this helped!
