Select the correct answers. if sides bd and dc have the same length, what is the length of side bc?

Hello! The answer is 4. We know this by:

Because BD and DC are equal we only need to find the length of BD and plug it into the pythagorean theory. (a²+b²=c² where c is the hypotenuse.)

So we find BD by using the pythagorean theory. BA = a and AD=b and BD=c. Plug it all in and we get 1²+1²=BD². We get 2=BD, now we need to take the square root of 2 to get 1.414213562.

Now that we know BD we also know DC so we can plug them into to this: BD² +DC²=BC².

1.414213562²+1.414213562²=4 and the square root of that is 2.

I hope this helped!

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
