Ik think your answer is 1

I’m assuming it’s a right triangle and you’re finding the hypotenuse. C is always the hypotenuse.

a^2+b^2=c^2

8^2+7^2=c^2

64+49=c^2

113=c^2

c=sqrt113

If it’s another side just sub it in.

8 is largest so it’s c.

using the same formula

64=49+b^2

64-49=b^2

15=b^2

b=sqrt15
