Question

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

Answer 1

Hypotenus sqre=perpendicular square+Base square
=12^2+9^2
=144+81
=225
Hypotenus=15(15^2=225)

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!!
