By alternate interior angles, DCA = CAB. All angles in a triangle add up to 180. Can you solve it?
How? Must be dark magic, or maybe a typo.
Hint:
Shaded = Square - 4 quarter circle
4 quarter circles = full circle
Full circle area = \({\pi}r^2\)
Square area = \(s^2\)
In this case, the side of the square is twice the radius of the circle.

As seen by the example f(x) = (x + 1)/(-x + 1), a + d = 2.
The complex numbers that work are 1, 1 + i, -1, and i.
mathway says it is equal to 2 + 3^(1/3).
Hint: It is a 45 - 45 - 90 triangle.
That means the area is (leg times leg) divided by two. The leg is \(\frac{6\sqrt{2}}{\sqrt{2}}\).
The answer is 100-25pi

T+3T+T-13=72
5T-13=72
5T=85
T=17

I used mathway, but it said that it was out of it's reach. It cannot solve it.
Let the side lengths be x and y units.
x+y+x+y36
2x+2y=36
x+y=18
y=5x
6x=18
x=3
15*4=60..
32 pi + 8 pi = 40 pi.
Square A area: x*x=x^2
Square B area: 4x*4x=16x^2
x/16x^2=1/16- is the ratio between square A and square B.
First circle: pi(20)^2=400pi inches squared:
Second cirle"pi(20/2)^2=100 pi inches squared.
Thus, 400pi-100pi=300 pi inches squared(square inches).
PQ is a straight line, so It has to measure one-eighty(180) degrees.
x+x+x+x+x=180
5x=180
x=36
x=thrity-six(36) degrees.
90-y=10
y=90-10
y=80 degrees,
The measure of angle M is eighty(80) degrees,
