hey mate
here is your answer
the triangle will be right angled traingle as it satisfies Pythagoras theorem
5²=3²+4²
let the radius of the circle be x
thus,
4-x+3-x=5
=>7-2x=5
=>-2x=-2
=>x=1 (answer)

Just for understanding purposes... why did you say that 4-x+3-x = 5
Why does it equal five
see because tangents drawn from external point
are equal
