Question

20,15,25 cm triangle inercircle radius determine

Answer 1

Answer:

infamous=5cm

Step-by-step explanation:

Formula for infamous: area/(semi perimeter)

S= (20+15+25)/2

=60/2

=30

Area(heron's formula)=√s(s-a)(s-b)(s-c)

=√30×(30-20)×(30-15)×(30-25)

=√30×10×15×5

=3×10×5

=150

Inradius = Area/S

=150/30

=5 cm

Therefore in radius is equal to 5cm
