Question

Triangle ABC is right-angled at vertex A. Calculate the length of BC, if
AB = 18 cm and AC = 24 cm.​

Answer 1

Answer:

By using Pythagoras theorem.

H*2=B*2+P*2

AC*2 = AB*2 + BC*2

24*2=18*2+BC*2

= 576= 324 + BC*2

= 576-324=BC*2

= 252 =BC*2

BC*2=252

BC= underoot 252

BC= 4 underoot 73.

Hope it's helpful to you.

According to my point of view this is the correct answer.
