Question

In a right angled triangle ABC B=90°
If AB = 3cm, BC = 4cm, find Ac.​

Answer 1

Here is your answer hope it helps you

Answer 2

Answer:

Let the length of AC,BC=n cm

given that AB=3cm

BC=4cm

angle ABC = 90°

${ac}^{2}= {ab}^{2} + {bc}^{2}$

${n}^{2} = {3}^{2} + {4}^{2} \\{n}^{2} = {9}^{2} + {16}^{2} \\ \sqrt[2]{n} = \sqrt{25} \\n = 5$

hence the length of AC=5cm....
