Question

*If the longest side in a right triangle ABC is 13 cm and one side making a right angle is 5 cm ,what is the length of the other side making a right angle?​

Answer 1

Answer:

other side is 12 cm

Step-by-step explanation:

hypotenuse = 13cm

side containing right angle = 5cm

let the other side be x

therefore by Pythogoras theorem

13^2 = 5^2 +x^2

x^2=13^2-5^2

x=√169-25

x=√144

x=12

Answer 2

Answer:

12 cm

Step-by-step explanation:

hypotenuse(longest side)=13 cm

one side=5 cm

Let the other side be x

By pythagorus theorem,

13^2=5^2+x^2

169=25+x^2

x^2=169-25

x^2=144

x=square root of 144

x=12

Length of other side=12 cm
