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!

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
