Question

find the hypotenuse if one side is 12 cm and the other side is 5 cm

Answer 1

Answer:

13cm

Step-by-step explanation:

Using Pythagoras theorem

12² + 5² = hypoteneuse²

144 + 25 = 139

hypoteneuse = root of 139

hypoteneuse = 13cm

Answer 2

Answer:

Hypotenuse $=13cm$

Step-by-step explanation:

By Pythagorean theorem,

hypotenuse $=\sqrt{side^{2}+side^{2} }$

Given one side $=5cm$ and the other side $=12cm$.

Therefore, hypotenuse

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

hence the answer
