Question

If 13 and 5 are two number of Pythagorean triple find the third number​

Answer 1

Answer:

12

Step-by-step explanation:

13²=5²+x²

x=root 13²-5²

x=root169-25

x=root144

x=12

Answer 2

Answer:

12

Step-by-step explanation:

Through Pythogoras theorem:-

We know that

(Hypotenuse)^2=(Base)^2+(Perpendicular)^2

lets take the Hypotenuse AC = 13 and Base AB = 5

therefore,

AC^2=AB^2+BC^2

13^2=5^2+BC^2

169=25+BC^2

144=BC^2

$\sqrt{144}$ = BC

therefore,

BC=12
