Angles DBA and CBE are congruent because they form a vertical pair.
The interior angles of any triangle sum to 180º in measure, so it follows that angles A and E must be congruent.

Answer:
1,100 is your area
Step-by-step explanation:
First we cut the shape into three, two triangles and a square, the formula to find the area of a square is A=a^2 (a is the side)
A=25^2
A=625
now to find the triangles the formula to find the are we use the right angled triangle formula twice which is A=a*b/2
A=25*19/2
A=475/2
A=237.5
now add them all up
625+237.5+237.5=
1,100
Answer: The three numbers are 8, 12 and 20.
Explanation:
Let k be the ratio of the numbers
The numbers: 2k, 3k, 5k
(2k)^2 + (3k)^2 (5k)^2 = 608
4k^2 + 9k^2 + 25k^2 = 608
38k^2 = 608
k^2 = 16
k = 4
Hence, the three numbers are 8, 12 and 20.
