Question

I don’t really know what to do, can someone help me?

Answer 1

x = 31˚

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˚

Answer 2

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°
