Question

Which of the following is not a pythagorean triple?

a. (6,8,10)
b.(4,6,7)
c.(5,12,13)
d.(9,12,15)

Answer 1

The answer is b.(4,6,7)

Explanation:

I used this formula on each.

Pythagorean theorem: a² + b² = c²

a^2 = 4^2 = 16

b^2 = 6^2 = 36

16+36= 52

√52 = 7.21110255093

The other three gave an exact awnser but b.(4,6,7) didn't even though close.

Answer 2

B.

Explanation:

(4, 6, 7)
