Question

In a right angled triangle ABC it is given that the hypotenuse AC = 2.5 cm and the side AB = 1.5 CM. Calculate the side of BC?

Answer 1

I have done it by using Pythagoras theoram

Answer 2

Given: AC=2.5 cm
AB=1.5 cm
To find: BC
WE KNOW Pythagoras theroem
AC^2=AB^2+BC^2
(2.5)^2=(1.5)^2+BC^2
6.25=2.25+BC^2
6.25-2.25=BC^2
4.00=BC^2
under root 4.00=BC
THEREFORE, BC=2.00 cm
