Please help!
AnnyKZ [126]

answer:

7.81

Step-by-step explanation:

ohh i like these questions this is the pythagorean theorem

1) a2+b2=c2

2) 5(2)+6(2)=c2

3) 25+36=c2

4) 61=c2

5) sqr root it

6) 7.81

Here are the senteces:

If those two were both the legs they would give us the answer of 7.81

gives us only two options of answers  and the other choice is putting

one of those options as a hypotenuse.So our chance for the third side

being 7.81 is 50% chance.

have a good day

The answer using Pythagorean theorem
OverLord2011 [107]

Answer: 12.32 is the answer.


Step-by-step explanation: Using the pythagorean thereom we can solve this by using the formula A^2+B^2=C^2.

We substitute in the values,

17^2+B^2=21^2.

Now we simplify.

289+B^2=441

We subtract the 289 from both sides,

B^2=152                                                                                                                                                            

Now we use square root to find the answer.

12.32 is the answer.

Hope this helps!
