Question

the hypotenuse of a right angled triangle is 25 CM if one of the remaining two sides is 15cm,find the length of its third side
​

Answer 1

Step-by-step explanation:

hypotenuse of right angle triangle = 25 cm

one side of right angle triangle = 15 cm

other side = x cm

we use Pythagoras theorem to find out the 3rd side

hyp² = base² + height ²

${25}^{2} = {15}^{2} + {x}^{2} \\ 625 = 225 + {x}^{2} \\ {x}^{2} = 625 - 225 \\ {x}^{2} = 400 \\ x = \sqrt{400} \\ x = 20$

therefore the third side = 20 cm

Hope you get your answer

Answer 2

Answer:

the answer is 20cm^2 !!!!!!!!!

Step-by-step explanation:

let,the other side be x

According to Pythagoras theory,

hypotenuse^2=base ^2+height^2

(25cm)^2=(15cm)^2+x^2

x^2=(25cm)^2-(15cm)^2

x^2=625cm^2-225cm^2

x^2=400cm^2

x=√400cm^2

x=20cm
