Answer:
The length of XY is either 10 or 2.5.
Step-by-step explanation:
Given information: ZY = 5, XC = 3 and DC = 4.
Case 1: Rectangle ABCD is smaller than ZBXY.
The opposite sides of the rectangle are same.



The length of ABCD is 4 and width of ABCD is 2. The width of ZBXY is 5. The corresponding sides of the similar rectangles are is in the same proportion.



Therefore the value of XY is 10.
Case 2: Rectangle ABCD is larger than ZBXY.



The length of ABCD is 4 and width of ABCD is 8. The width of ZBXY is 5. The corresponding sides of the similar rectangles are is in the same proportion.



Therefore the value of XY is 2.5.
Answer:
m = -2
Step-by-step explanation:
Since 10 is smaller than 12, we have to subtract to get a negative number.
10 - 12 = -2
Area =
The diameter is double the length of the radius
7 ÷ 2 = 3.5
3.5 × 3.5 = 12.25
= 38.4845100064751
38.4845100064751 rounded to the nearest tenth is 38.5
This would be cos^2x, because when you foil out the equation you get 1-sin^2(x).
1-sin^2(x)=cos^2(x)
