Answer 3

yes

Answer 4

Ok, tell me then, what is the formula for the Pythagorean Theorem? That is what we need to know first to find out this answer.

Answer 5

a^2+b^2=c^2 that is sum of square of two sides equal to square of third side

Answer 6

a^2+b^2=c^2

Answer 7

so then what

Answer 8

Ok, remember that the hypotenuse is the longest side of a possible right triangle and is inserted in that formula as C while the other two sides are inserted in any order as A and B, try and plug in the sides keeping this in mind for the first possible answer, A.

Answer 9

so 6^2+8^2=11^2 ?

Answer 10

no its not A

Answer 11

Right! Now try and repeat this for B.

Answer 12

its B right?

Answer 13

Try and use the pythagorean therom to find out.
