Answer:
The answer to your question is: x = 62°
Explanation:
Data
This is an isosceles triangle because two sides have the same length. Then two angles have the same measure.
Also, the sum of the internal angles in a triangle is 180°.
x° + x° + 56° = 180
2x° = 180 - 56
2x° = 124
x° = 124 /2
x° = 62
