Question

find the length of the hypotenuse of a right triangle, the other two sides of which measures 9cm and 12 cm. ​

Answer 1

Answer:

using pythagoras theorem

h² = b² +p²

h² = 9² + 12²

h² = 81 + 144

h² = 225

h² = 15²

h = 15 cm

length of the hypotenuse is 15 cm

Answer 2

Answer:

In ∆ABC, /_ B = 90°

.･.By Hypotenuse side theorem

(AC)^2 = (AB)^2 + (BC)^2

= (9)^2 + (12)^2

= 81 + 144

= 225

AC = 225. (Taking square root on both side)

= 15cm

.･. The lenght of hypotenuse of right angle triangle is 15cm

Hope you understood mate!!
