its hypotenuse.
7. The lengths of the sides of some triangles are given below. Which of them are right-angled?
(i) a = 15 cm, b = 20 cm and c = 25 cm
(ii) a = 9 cm, b = 12 cm and c = 16 cm
(iii) a = 10 cm, b = 24 cm and c = 26 cm

Answer 1

Answer:

Simple question

Step-by-step explanation:

Try by your self

Answer 2

Step-by-step explanation:

Let AB=10cm

Hypotenuse (AC)=26cm

BC=?

Then, by Pythagoras theorem

AC 2

=AB 2 +BC 2

c 2

=a 2 +b 2

c 2 =6 2 +(4.5) 2

c 2=36+20.25

c 2=56.25

Sending powers 2 from LHS to RHS it becomes square root

c= 56.25

c=7.5cm

The length of hypotenuse of a triangle is 7.5cm
