Answer:
Decagon
Step-by-step explanation:
We can use the general equation to determine the sum of interior angles:
Since we know the sum of interior angles (I.A.) is 1440°, we must figure out n - the number of sides and so:
Since n=10 this means that it is a 10 sided shape meaning it's a decagon.
Answer:
x=86 , y=94, z=75 , first option is the answer
Answer:
Perimeter of rectangle = 36 meters
Step-by-step explanation:
We have given,
Length of rectangle = 14 meters
Width of rectangle = 4 meters
Perimeter of rectangle given as:
Perimeter = 2 (Length + width)
To get perimeter plug values of length and width into perimeter formula.
i.e Perimeter = 2 ( 14 + 4)
Perimeter = 2 * 18
Perimeter = 36 meters
Hence the perimeter of rectangle is 36 meters
