Given that the central angle of a polygon is 18, then the number of sides of the polygon will be:
360/18
=20 sides
thus the side length will be:
144/20
=7.2 ft
hence the area will b given by:
p=s×n
a=s/[2tan(180)/n]
where:
Area=(a×p)/2
p=perimeter, s=side length, n=number of sides
p=7.2×20=144
a=7.2/[2tan (180/20)]=22.73
thus
A=(144×22.73)/2
A=1632.524 ft²
The circumference formula is pi times diameter. So first divide 56.52 by 3.14 and that is 18. So the diameter is 18
Answer:
13 all three angles =60 in total they equal 180
14) I believe x = 32.5 Am not sure though.
Step-by-step explanation:
That is the only question i can answer but to help you with this all triangles big or small the total of all the angles combined = 180
32% of 19 is 6.08%
So your answer is: 6.08%
Answer:
x=-8
Step-by-step explanation:
First you should add 5x+67 and 5x+61 together which is 10x+128
Then you set that equal to 3x+72 which would be: 10x+128=3x+72
After that subtract 3x from both sides which leaves you with: 7x+128=72
Then subtract 128 from 72 which gives you: 7x=-56
Then divide by 7 which gives you x equals negative eight
