Question

In ΔABC, ∠A = 90°, BC =13 cm, AB =12 cm, which of the following is the value of AC?

Answer 1

Given:- A ∆ABC in which angle A = 90° , BC= 13 cm, AB= 12cm.

To Find: Value if AC

Solution :-
We know in right∆ABC,

By Pythagoras Theorem,
BC^2 = AB^2 + CA^2
13^2 = 12^2 + CA^2
CA^2 = 169 -144 = 25
AC = 5cm.

Hope it helps....❤️❤️
