Question

ABC is a right triangle right angled at B such that BC is equal to 6 cm and a b is equal to 8 cm find the radius of its in circle​

Answer 1

Answer:

the answer is 2 cm

Step-by-step explanation:

AB²+BC²=AC²

8²+6²=AC²

AC²=64+36=100

AC=√100=10

Radius of in circle=area of ∆ABC/Semiperimetre

of ∆ABC

=(½*base*height)/(AB+BC+AC/2)

=(½*8*6)/ (8+6+10/2)

=24/12

=2cm
