Answer:
68
Step-by-step explanation:
Given is an isosceles triangle, therefore measures angles opposite to equal sides would be equal.
Hence,
56° + 56° + x° = 180°
112° + x° = 180°
x° = 180° - 112°
x° = 68°
x = 68
The triangle is isosceles as two sides have same length
Angles opposite to same sides have same value, therefore two of them equal to 56°
