Question

The hypotenuse of one side of a right angled triangle are 5cm and 4cm respectively. what is the length of the other side

​

Answer 1

Hypotenuse is the longest side in a triangle.

a^2=b^2+c^2.

5^2=4^2+c^2.

c^2=25-16.

c^2=9.

c=√9.

c=3cm.

Answer 2

Answer: 3cm

Step-by-step explanation:

We can use Pythagorean’s theorem to find that other side:

a^2 + b^2 = c^2
a^2 + 4^2 = 5^2
a^2 = 25 - 16
a^2 = 9
a = 3

Therefore, the other side is 3cm
