Question

ABC is triangle, right- angled at A. if AB=18cm AC=24cm. find BC​

Answer 1

Answer:

30 cm

Step-by-step explanation:

In the given traingle, hypotenuse = BC

In a right angled triagle, hypotenuse = √(a square + b square)

where a and b are the other two sides

Here, a = 18 and b = 24

hypotenuse BC = √(18 square + 24 square)

=√(324+576)

=√900

= 30 cm

Answer 2

Answer:

Hence, according to Pythagoras theorem

AB ^2 +AC ^2 =BC ^2

⇒ 18 ^2+24 ^2

=BC⇒BC=

900

=30 cm
