1.	The equal sides of an isosceles triangle are 8 centimetres long and theradius of its circumcircle is 5 centimetres. Calculate the length of itsthird side.(2)
Answer» x^2 + y^2 = 25x^2 + (5+y)^2 = 64(25-y^2 ) + 25 + 10y + y^2 = 6410y = 14y = 1.4x^2 + (1.4)^2 = 25x = 4.8length of 3rd side is 9.6 cm The length of its third side Thank you

Answer»

x^2 + y^2 = 25x^2 + (5+y)^2 = 64(25-y^2 ) + 25 + 10y + y^2 = 6410y = 14y = 1.4x^2 + (1.4)^2 = 25x = 4.8length of 3rd side is 9.6 cm

The length of its third side

Thank you
