Question

find the length of hypotenuse of right angle triangle whose other two sides are 9 cm​

Answer 1

Answer:

12.72cm

Step-by-step explanation:

Let the triangle be right angled at B.

Let BC be the base and AC the hypotenuse.

According to Pythagoras Theorem,

AC^2 = BC^2 + AB^2

By substituting the values,

AC^2 = 9^2 + 9^2

AC^2 = 81 + 81

AC^2 = 162

AC = √162

AC = 12.72cm

Answer 2

Step-by-step explanation:

formula of hypotenuse is a^2+b^2=c^2

Here,c=hypotenuse

therfore,

(9)^2+(9)^2=c^2

81+81=c^2

162=c^2

c=√162

C=12.73
