Answer:
Where is the triangle
Step-by-step explanation:
3/4+z=5/6
Find the common denominator which is 12 for 3/4 and 5/6.
Multiply by 3 for 3/4.
Multiply by 2 for 5/6.
3(3)/4(3)=9/12
5(2)/6(2)=10/12
9/12+z=10/12
Move 9/12 to the other side. Sign changes from 9/12 to -9/12.
9/12-9/12+z=10/12-9/12
z=1/12
Answer: z= 1/12

Answer:
A= 1038 in²....
Step-by-step explanation:
There are several ways to find the area of a regular hexagon
In a regular hexagon, split the figure into triangles.
Find the area of one triangle.
Multiply this value by six.
We will apply the formula of area of regular polygon:
A= 1/2r²nsin(360/n)
r = radius
n = number of sides of the regular polygon
We know that,
r= 20 in
n= 6
Now substitute the values in the formula:
A= 1/2(20)²(6)sin(360/6)
A= (20)²(3)sin(360/6)
A= (20)²(3)sin(60)
A=3*(20)² *√3/2
A= 1200 * √3/2
A= 600*√3
A= 1038 in²....
Therefore the approximate area of hexagon is 1038 in²....
