Question

find the hypotenuse if the two sides of a right angled triangle are 3 cm and 4 cm​

Answer 1

Answer:

By Pythagoras theorem

(Hypotenuse)^2 = (3)^2 + (4)^2

= 9 + 16

= 25

Thus, Hypotenuse = (25)^1/2

Hypotenuse = 5 cm

Answer 2

Answer:

5 cm

Step-by-step explanation:

According to pythgoras theorem

hypotenuse square= summation of square of the other two sides.

let c be the hypotenuse and a and b be the other two sides.

c2=a2 +b2

c2=(3)2 + (4)2

c2=9+16

c2=25

c=5

Therefore length of hypotenuse is 5 cm
