Answer:
angle y= 90
angle z= 45
angle x= 45
Step-by-step explanation:
Atriangle has 180 degrees. The y angle is 90 degrees because whenever a shape has the square thing it means it is 90 degrees. so 180-90 = 90. Since both of the other angles are the same 90/2 = 45. so angle y= 90 degrees and angle z= 45 degrees and angle x=45 degrees
The hypotenuse is the longer of the 3 sides:

Step-by-step explanation:
The area of rectangle ABCD can be expressed in simplified form as: 8y^2 - 10y.
<h3>How to Calculate the Area of a Rectangle?</h3>
The area of a rectangle is calculated using:
Area = (length)(height).
We are given the following:
Length of rectangle ABCD = side DC = 4y - 5
Height of rectangle ABCD = side AD = 2y
The area of rectangle ABCD = (length)(height) = (4y - 5)(2y).
Expand the expression
The area of rectangle ABCD = 2y(4y) - 2y(5) [distributive property of multiplication]
The area of rectangle ABCD = 8y^2 - 10y
Thus, the area of rectangle ABCD can be expressed in simplified form as: 8y^2 - 10y.
