The sum of exterior angles of a polygon = 360<span>°
Thus, the eighth exterior angle is equal to
360</span>° - (42° + 55° + 39° + 20° + 62° + 45° + 47°) = 50<span>°</span>
Answer:
5.38 inches
Step-by-step explanation:
The formula for Area of an Heptagon
= A=7/4a²cot(180°/7)
Area = 105in²
Side a = ?
The formula for Side a
= √4A ×tan (180°/7)/7
= √4 × 105 × tan (180°/7) /7
= 5.37536 inches
Approximately = 5.38 inches.
Sin50° = BC/3
3sin50° = BC
BC = 2.981
