Answer:
Either x = 124 deg or x = 76 deg depending on which angle measure appears twice.
Step-by-step explanation:
An isosceles triangle has at least two congruent angles. You don;t say which angles are congruent, and there is no figure, so there are two possibilities.
1) Two angles measure 28 deg, and one angle measure x degrees.
2) Two angles measure x degrees, and one angle measures 28 deg.
Possibility 1)
28 + 28 + x = 180
x + 56 = 180
x = 124
Possibility 2)
x + x + 28 = 180
2x + 28 = 180
2x = 152
x = 76
