Step-by-step explanation:
Each interior angle=140°
(n-2)180°/n=140°
180°n-360°/n=140°
180°n-360°=140°n
180°-140°=360°
40°n=360°
n=360°/40°
n=9
Hence, the number of sides of the polygon is 9.
It is nonagon .
Answer:
Lateral Area = Area of 2 triangle + Area of slant rectangle + area of back rectangle
Lateral Area = (5m)(3m) + (6m) (36m) + (3m) (36m)
LA = 15m² + 216m² + 108m²
LA = 339 m²
SA = (5m)(3m) + (6m) (36m) + (3m) (36m) + (5m)(36m)
SA = 15m² + 216m² + 108m² + 180 m²
SA = 519 m²
C) x+3
first one factors to (x+3)(x-3)
second factors to (x+3)(x-2)
6/10= 3/5
Or 6/10=6/10
Or 6/10= .6
Hey there!
4(12 + 6)
4(12) + 4(6)
4(12) = 48
4(6) = 24
48 + 24 = ?
48 + 24 = 72
Answer: 72 ☑️
Good luck on your assignment and enjoy your day!
