Question

∆ABC IS in right angeled at c if ac=5 and bc=12 find the leangth of ab​

Answer 1

Answer:

13 cm

Step-by-step explanation:

C is a right angle so AB is the hypotenuse

Thus AB²=AC²+BC²

=25+144=169

Thus AB=√169=13 cm

Answer 2

Question:

∆ABC is in right angled at C if AC=5 and BC=12 find the length of AB?

Answer:

13cm

Step-by-step explanation:

We can Get to know AB side by using Pythagoras theorem:

⇒$(AB)^2=(BC)^2+(AC)^2$

We know the value of

AC = 5cm

BC = 12cm

We will substitute into the Formula

⇒$(AB)^2=(12)^2+(5)^2$

⇒$(AB)^2=(144)+(25)$

⇒$(AB)^2=169$

⇒$(AB) =$ $\sqrt{169}$

⇒$AB= 13cm$

Hence the other side of triangle is 13cm.
