Question

In triangle ABC. angle B=90, AB=4cm, BC=3cm then find AC​

Answer 1

Answ

Hope it helps.friends the answer is AC=5cm

Answer 2

The length of side AC is 5 cm.

Step-by-step explanation:

Given:

In triangle ABC.

m∠ B=90,

AB = 4 cm,

BC = 3 cm

we need to find AC​.

Now By Using Pythagoras theorem which states.

"Sum of square of two sides of a right angled triangle is equal to square of the third side."

framing in equation form we get;

$AC^2 = AB^2+BC^2\\\\AC^2 = 3^2+4^2\\\\AC^2= 9+16\\\\AC^2 =25$

Now taking square root on both side we get;

$\sqrt{AC^2} = \sqrt{25} \\\\AC =5\ cm$

Hence The length of side AC is 5 cm.
