Question

find the length of hypotenuse of a right angled triangle the other two sides are 9 cm and 12 cm​

Answer 1

Answer:

Hey mate!!!

Step-by-step explanation:

By pythagorus theorem,

(hyp)^2= (base)^2 + (height)^2

SO, hyp^2= (9)^2+ (12)^2

hyp^2 = 81 + 144

hyp^2 = 225

hyp = √225

hyp = 15 .

so the hypotenuse of the right angled triangle = 15cm

HOPE IT HELPS

PLEASE MARK AS THE BEST ANSWER...

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!!
