Answer:   2 cm

Step-by-step explanation:

AC = (Pythagoras Theorem) = √(6² +8²) = 10cm \

Radius of the incircle = area/semi perimeter

Area of the triangle = 1/2*b*h = 1/2*6*8 = 24cm²

semi perimeter = (AB + BC + CA) / 2  = 24/2 = 12cm

Radius of the incircle = area/semi perimeter

                                   = 24/12 = 2cm
