In triangle ABC,
Angle ABC=90°
by the pythagoras theorem,
AC^2=AB^2+BC^2
24^2=10^2+BC^2
576=100+BC^2
BC^2=576-100
BC^2=476
BC=21.8

Given: Angle B is 90°.
AC is 24 cm.
AB is 10 cm.
To find: BC is?
Solution: By pythagoras theorem
AC^2 = AB^2 + BC^2
24^2 = 10^2 + BC^2
576 = 100 + BC^2
BC^2 = 576 - 100
BC^2 = 476
BC= 21.817
Hence, BC is 21.8 cm.
