An isosceles triangle has 2 congruent sides and the is an obtuse angle.
To find an average you add the data values and divide by how many value you have. Since we don't know the one cubs weight we'll use a variable. Set up an equation to find average using x as the weight that is unknown.
Now solve.
(294 + 268 + x )/3 = 288
Multiply both sides by 3 to clear the fraction.
(294 + 268 + x) = 864
Add the left side.
562 + x = 864
Subtract 563 from both sides
x = 302
