Answer:
C
Step-by-step explanation:
∠CDE = 0.5( mEC - m CE )
The arcs CE and EC must add to 360°, thus
arc EC = 360° - 105° = 255°, hence
∠CDE = 0.5(255 - 105)° = 0.5 × 150° = 75° → C
First, multiply 20 x 25 to find the amount of chairs per section:
20 x 25 = 500
Now, multiply 500 x 4 to find the total amount of chairs for 4 sections:
500 x 4 = 2000
