Question

in a right triangle ABC,if angle 900,ab=5cm , bc=12cm ,the lenghth of ac is ​

Answer 1

Answer:

ac^2 = 25 + 144=169

Ac = 13 cm

Answer 2

Answer :

ac =13 cm

Step by step solution :

Δ ABC is a right angle triangle

∴ by pythagoras theorem

ab^2 + bc^2 = ac^2

5^2 + 12^2 = (ac)^2

25 + 144 = (ac)^2

169 = (ac)^2

taking square root both sides

13 = ac

∴ac = 13cm
