Answer:

x = 79

Explanation:

All triangles have a sum of 180°. Knowing this, we can solve for the unknown angle.

56 + 23 + ? = 180

79 + ? = 180

? = 101

The variable x is known as an exterior angle. That and the angle we just solved for are supplementary meaning they add up to 180°.

101 + x = 180

x = 79
