Step-by-step explanation:
What is the length of the unlabeled side?
The formula of Pythagoras theorem is expressed as, Hypotenuse² = Base²+ Height². This is also written as, c² = a² + b²; where 'c' is the hypotenuse and 'a' and 'b' are the two legs of the right-angled triangle.
√(13²-12²) =
√(169 - 144) =
√25 =
5
