an isosceles triangle with sides 13 13 10 and there is a circle inscribed it .find the radius of circle?	Choose the correct option
A) 1.32	B) 3.33	C) 3.58	D) 4.34	E) 5.18
height of triangle = √(13^2 - (10/2)^2) = 12   area of triangle = r * s   where, r = radius of inscribed circle &amp; s=(a+b+c)/2   area of triangle = 1/2 *b*h = 1/2 *10 *12= 
<gadget id="calculator">1/2 *10 *12</gadget>
<output>60</output>
60   s= (13+13+10)/2= 
<gadget id="calculator">(13+13+10)/2</gadget>
<output>18</output>
18   r= area of triangle / s = 60/18 = 10/3 = 3.33   ANSWER:3.33
<result>B</result>
