Why?
Because if you draw a line from A to D to make a triangle AED, then triangle all angle add up equal 180.
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:
Subtracted 3 from (24+3)
Step-by-step explanation:
3m - 3 + 3
24 - 3 + 3
Since the adding and subtracting go left to right, you can do them in that order.
21+3 = 24.
Now which one gives us 24?
(24+3) - 3
