Is a triangle with sides of length 6ft, 21 ft, 23 ft. a right triangle?

No

Step-by-step explanation:

By using the Pythagoras theorem, it can be easily determined that whether the triangle is right triangle or not.

Thus, where where a and b are the legs and c is the hypotenuse.

Let a=6ft, b=21ft and c=23ft, then

which is not possible, therefore the given triangle is not right triangle because it does not satisfy the Pythagoras theorem.

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
