Respuesta :
123° and the adjacent angle (The one next to it, but inside the triangle) added together equal 180°. 180 - 123 = 57°.
The three angles of a triangle, when added up, equal 180°.
So x + 57 + 92 = 180
x + 149 = 180
x = 31°

Answer:
x = 31˚
Step-by-step explanation:
The straight line will always have 180˚. 180 - 123 = 57˚.
A triangle will always have the angles add up to 180˚. 180 - 57 - 92 = 31˚
x = 31˚
