An isosceles triangle has sides A, B, and C, such that sides A and B have the same length. Side C has a length of #16 # and the triangle has an area of #72 #. What are the lengths of sides A and B?
Let the length of side A or B = x and base is 16. So the height is
Now the area of triangle = 1/2 * base * height
or, x =
