Question

the hypotenuse of a right triangle is 13cm long.if one of its legs is 12cm , find the length of the other leg of the triangle​

Answer 1

Answer:

h^2=p^2+b^2

13*13=12*12+b^2

b^2=169-144

b^2=25

b=5.

Answer 2

Answer:

Step-by-step explanation:

according to pythagoras theorem

a^2+b^2=c^2

so let a be 12cm

and c is 13cm

so 12^2+b^2=13^2

144+b^2=169

b^2=169-144

b^2=25

b=root of 25

therefore b=5

hence the length of the third side is 5cm

hope this helped ;)
