A TRIANGLE IS INSCRIBED IN A CIRCLE SUCH THAT ONE OF ITS SIDES IS A DIAMETER OF THE CIRCLE.IF THE RADIUS OF THE CIRCLE IS 30.5 CM AND ONE OF THE SIDES IS 60 CM, FIND THE AREA OF THE TRIANGLE?

A triangle on a diameter makes a right angle at the circle
So let the third side be x
x^2 + 60^2 = 61^2
x = √121 = 11
so the area = (1/2)(60)(11) = 330
