Question

Plssss Help!!!

Answer 1

Answer:

C

Step-by-step explanation:

First, let us try the first on:

sqrt (5^2+4^2)=sqrt 41 so it can't be A

Second one:

sqrt (6^2+7^2)=sqrt 85, no

Third one:

sqrt (8^2+6^2)=sqrt 100 = 10, so it is C

Answer 2

Answer:

C

Step-by-step explanation:

I will just say how to do C but it is the same for all of the other ones.

First I write a²+b²=c²

Then I put in the numbers and get 6²+8²=10²

After that I do the ² to all of them to get 36+64=100

Next I add 64 and 36, which equals 100

100=100
