Question

with
(b) ABC is a right-angled triangle with a
= 6 cm and BC = 8 cm. A circle
centre O has been inscribed insid
triangle. Calculate the value of x.
radius of the inscribed circle. ​

Answer 1

Answer:

to find the radius=x

we have to find the are of the triangle and have to divide it by the semi perimeter of the triangle

the area of the triangle=(1/2×6×8) =24 cm^2

the semi perimeter =( 8+6+10/2)=12cm^2

radius =x=(24/12)cm^2=2cm
