Question

What is the length of the hypotenuse? 12 5 X= Help

Answer 1

Answer:

13

Step-by-step explanation:

$\sqrt{5^{2} + 12^{2}} = \sqrt{169} \\ \\ \sqrt{169} = 13$

a²+b²=c²

Answer 2

Answer:

x = 13

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = x^2

25+144 = x^2

169 = x^2

Taking the square root of each side

sqrt(169) = sqrt(x^2)

13 =x
