Answer: 20°</h2>
<h3>
Step-by-step explanation:</h3>
Supplementary angles sum up to 180 °
Complementary angles sum up to 90°.
The supplement of 110° = 180° - 110° = 70°
The complement of 70° = 90° - 70° = 20°
<u>Simplier version:</u>
The complement of the supplement of 110° = (90° - (180° - 110°))
= 20°
