Hey there,
Since ΔABC is right angled so,
AB²=17²-15²=289-225=64
So AB=√64=8cm
According to formula Inradius=Area/Semiperimeter
Since perimeter=8+15+17=40cm
So semiperimeter=40/2=20cm
Area=1/2*b*h=1/2*15*8=60cm²
Putting in formula Inradius=Area/Semiperimetre
we get R=60cm²/20cm=3cm
PLEASE MARK AS BRAINLIEST IF HELPFUL!!!
