It is given in the question that
BD is the median. So it divides the opposite sides in two equal parts .
Therefore in triangles BAD and BCD,
AB and AC are congruent because of isosceles triangle.
AD and CD are congruent because of the median BD.
And BD and BD are congruent .
So the two triangles are congruent by SSS and the correct option is the first option .
4.2 +c = 8.1
c = 8.1 -4.2 = 3.9 . . . . subtract 4.2 from both sides
a.) 3.9 liters . . . . . is the appropriate choice
02 goes into 78 (39) times!

Im not sure what you need but here is the first equotion.
Answer:
2.4 miles per hours
Step-by-step explanation:
if she traveled 1/5 of a mile in order for you ro do this you must first teun it into a full mile so times it by the required amount to equal one which would be five.
1/5 of a mile x 5 = 1
you must do this also to the time
5 minutes x 5 = 25 minutes
it takes her 25 minutes to travel one mile so because miles per hour is a ration you must find the amount in hours and not minutes.
So you must divide the hour equivilent by 25 minutes.
so if 1 hour equals 60 minutes
60 divided by 25 = 2.4
that is how you find miles per hour
