Question

Find the length of the hypotenuse if the legs of a triangle are 5cm and 12 cm.

Question 5 options:

7cm


13cm


17cm


169cm

Answer 1

The correct answer is: [B]: " 13 cm" .
________________________________
c² = a² + b² ;

In which "c" is the hypotenuse;

a = 5 ;
b = 12 ;
c = ? ;

Solve for "c"

+√(c²) =√(a² + b²) ;

c = √(5² + 12²) ;

c = √(25 + 144) ;

c = √169 ;

c = 13 cm .
