Question

triangle ABC right angled at B in which AC is equal to 10 cm a b is equal to 8 cm

Answer 1

Therefore, BC =6 cm

Step-by-step explanation:

Given that $\triangle ABC$ has right angle B and AC =10 cm and AB=8cm

So,$AB^2+BC^2=AC^2$

⇔$8^2+BC^2=10^2$

⇔$BC^2$ =100-64

⇔$BC^2$ = 36

⇔BC =6 cm
