Question

the lenght of sides of a right triangle are 5cm and 12cm. what is lenght of is lenght of its hypotenuse

Answer 1

(h)^2=(5)^2+(12)^2
=25+144
=196
h^2=196
h=13 cm

hope this may help u

Answer 2

Here, Base(B) = 5 cm, Perpendicular(P) = 12 cm, Hypotenuese(H)= ?
Using Pythagoras Theorem,
H^2 = B^2 + P^2
H^2 = 5 X 5 + 12 X 12 
H^2 = 25 + 144
H^2 = 169
H X H = 13 X 13
H = 13 cm
Hence, the hypotenues of rt angled triange = 13 cm
