Answer:

squaroot of 39

Step-by-step explanation:

take ab to be the bc to be the base so finding midpoint of the hypotenuse we have 1/2 acsquared= ab squared+ bc squared

we get 1/2 ac squared = 6 squared+8 square which gives 100

sqrt{100} = 10 and a half of ten is 5

now we have another right angled triangle with DB as height DC as base and BC as hypotenuse and using the pythagoras theorem to find BD we have 8 squared minus 5 square which equals 39

find the square root of 39 to get the length of BD
