Question

if two sides of the right angle triangle are 3 and 4, then what is the length of the third side?​

Answer 1

Answer:

5 units

Step-by-step explanation:

In ️ABC

Angle B = 90°

By Pythagoras Theorem

AB² + BC² = AC²

3² + 4² = AC²

AC² = 9 + 16

AC² = 25

AC = 5

Answer 2

Step-by-step explanation:

given two sides of a right angled triangle are 3cm and 4 cm .

by using Pythagoras theorem,

hypotenuse square =side square + side square .

other side=

$\sqrt{3 {}^{2} + 4 {}^{2} } \\ \sqrt{9 + 16} \\ \sqrt{25 } \\ 5$

therefore third side is equal to 5
