Answer:
1. angle EBC
2. 20°
[tex] x = 180 - 160 \\ x = 20[/tex]
3. angle ABD
4. 134°
[tex] x = 180 - 46 \\ x = 134[/tex]
5. 90°
[tex]2x = 180 \\ x = \frac{180}{2} \\ \times = 90[/tex]
6.supplementary angle
note : the x represents the angles
* In other words when you add the measure of one angle in the pair with the other angle in the pair, they equal 180 degrees.
