Answer:
seventh interior angle=∠x=29°
Step-by-step explanation:
sum of interior angle of polygon is equal to 360°
let seventh angle of heptagon is x
∠x+47°+55°+62°+64°+54°+49°=360°
∠x=360°-(47°+55°+62°+64°+54°+49°)
∠x=360°-331°=29°
∠x=29°
seventh interior angle=∠x=29° answer
Answer:
451
Step-by-step explanation:
125 because it’s symmetrical between both
Tanα=5/12
α=arctan(5/12)°
α≈22.62° (to nearest hundredth of a degree)
