Answer:
Additional information required is
<DBA = 90°
Step-by-step explanation:
<DBA + <DBC = 180° [Linear pair]
=> <DBA = 180° - <DBC
=> <DBA = 180 - 90
=> <DBA = 90
Hence, both the angles <DBA = <DBC = 90°
As we know that when a perpendicular bisector bisects a straight line both the angles should be,
180° ÷ 2 = 90°
And above conditions also prove that
<DBA = <DBC = 90°
<em><u>Hence, DE is a perpendicular bisector of AC </u></em>
7003/24 = 291 19/24, can also be written as 291.791667
1004/37 = 27 5/36, can also be written as 27.135135
2548/46 = 55 18/46, can also be written as 55.391304
5781/46 = 125 31/46, can also be written as 125.673913

Answer:
a^2-3ab+2b^2
Step-by-step explanation:
(a-2b)(a-b)
a^2-2ab-ab+2b^2
a^2-3ab+2b^2
The answer is 42. Because 17+4=21 and 21 times 2= 42
