Answer: x in top right = 90°
x in bottom left = 90°
Step-by-step explanation:
The vertical angle of 110° = 110°. That angle is corresponding to x + 20°
110° - 20° = 90°
We know all of the interior angles of the triangle because:
1. Vertical angle to 20° = 20°
2. Supplementary angle to 110° = 70°
3. Other angle = 180 - 20 - 70 = 90°
The supplement to 90° = 90° , so the x in the bottom left = 90°
