Answer:
C = 100
Step-by-step explanation:
Supplementary angles equal 180 degrees
180 - 80 = 100
Answer:
m∠C = 100°
Step-by-step explanation:
Supplementary angles are angles that add up to 180°. We are given m∠D as 80°.
- This means that c + 80 = 180
Step 1: Subtract 80 from both sides.
- [tex]c+80-80=180-80[/tex]
- [tex]c=100[/tex]
Therefore, the answer is 100°.
