Answer:
54
Step-by-step explanation:
x-1=3
2xy=24
3+24=27
27·2=54
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 .

Step-by-step explanation:
Enter the x,y values in the box above. You may enter data in one of the following two formats:
Each xi,yi couple on separate lines:
x1,y1
x2,y2
x3,y3
x4,y4
x5,y5
Answer:
38 times
Step-by-step explanation:
A coin has two sides, so there is a 50% chance it will land on either side (assuming perfect conditions and that the coin cannot land vertically). With that in mind, if you flip a coin 76 times, 50% or 1/2 of the times the coin should land on tails. That is 36 times. (Once again, this is under perfect testing conditions. In real life, you probably wouldn't get an even split after only 76 flips.)
Hope this helps :)
