HELP ME OUT !!! im stressing out keep getting it wrong
Arlecino [84]

Answer:

x=24, y = 33/360 π×24^2/(sin^2(33° (degrees)))

Step-by-step explanation:

notice that x = MK = HM = 24.

Let the center of the circle be C.

Also, notice the radius of the circle can be expressed as the hypotenuse of HMC. Using some trig, we figure out that the radius is 24/sin(33 degrees).

Using the radius of the circle, we can figure out the circumference. The circumference is pi*r^2=(24/sin(33 degrees))^2*pi=pi*24^2/(sin(33 degrees)^2)

Lastly, notice that y = 33/360*circumference = 33/360 π×24^2/(sin^2(33° (degrees)))

hopefully this helped

How does the ratio of corresponding side lengths of the two quadrilaterals compare with the ratio of the areas of the quadrilate
Wittaler [7]

Answer:

The ratio of the areas would be the ratio of the side lengths squared.

Say the ratio of the side lengths is 1:2, the ratio of the areas would be 1:4. If the ratio of the sides were 2:3, the ratio of the areas would be 4:9.

Hope this helps
