Answer:
15x+5+22x+4+60=180
37x=180-60-5
37x=115
x=115/37
x=3
angle b
22*3+4=70°
angle c
15*3+5=50°
have a nice day . hope this helps
Answer:

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.
Technically the endpoints will be intersection of first endpoint between x=1 and y=-1second endpoint between x=-2 and y=2
so they are 1-i and -2+2i
