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>

Step-by-step explanation:
Answer:
Let us consider we are given.1.54 and 2.37.
So here for 1.54 you can do one set of the 100 and then 5 tenths and 4 hundredths.as well as for the 2.37 you can to 2 hundreds and 3 tenths as well as the 7 hundredths. So here we are adding these numbers 1.54 + 2.37 is 3.91.so answer is 3.91. You can do 3 hundreds and 9 tenths and 1 hundredths.
Step-by-step explanation:
Answer:
You do (Keep, Change, Flip)
so you keep 9/4
Then change the division sign to multiplication sign
Finally flip the next fraction (10/3) becomes 3/10
9/4 * 3/10 = (9*3)/(4*10) = 27/40
