Answer 1

out of each 3 numbers take the largest and square it

then take the Other and squre them - add the 2 squared numbers together

IF the sum of the 2 samller squares = the larger sqare then it is a right angle.

FOR INSTANCE

3,5, 4

the largest is 5 and 5^2 = 25

the other numbers are 3, and 4

3^2 + 4^2 = 9+16 = 25

so sides of 3,4 & 5 make a right angle triangle

do that with your sets of numbers to find the one where this is true...

Answer 2

so c?

Answer 3

it is best if YOU do the calculation. If someone gives the answer you will not have any better understanding.

Pythagoras theorem says in a right angle triangle with sides a, b , c



if c is the longest side then a^2 + b^2 = c^2
