What is the area of the regular heptagon shown below? (Round your answer
to the nearest whole number.)
231
22.15
A. 3566 sq. units
B. 1528 sq. units
C. 1783 sq. units
D. 3057 sq. units
y’all help please
Answer:
C
Step-by-step explanation:
A heptagon is a polygon with 7 triangles. (a)
Thus, The area (A) will be = 7a
[tex]The \ area \ of \ \ triangle \ = (1/2) \times b \times h[/tex]
where;
b = base
h = height
So;
[tex]7a = \dfrac{1}{2}(bh)[/tex]
where;
b = 22.15 unit and h = 23 unit
∴
[tex]A = \dfrac{7 \times b \times h}{2} \\ \\ A = \dfrac{7 \times 22.15 \times 23}{2} \\ \\ A = 1783.07 \ sq. units \\ \\ A \simeq 1783 \ sq. units \\ \\[/tex]

x+y=3 and x-ý=
x1 simultaneous equation
Answer:
y=1, x=2
Step-by-step explanation:
x+y=3
x-y=1
Using elimination method
x-x+y--y=3-1
2y= 2
y=1
Substitute y=1 into equation 2
x-1=1
x=1+1
x=2
Answer:
x=1!y=2 submitted that values in question u got answers see please likable
y varies directly as X. If X=2 and y=10. Find Y when X=7
Answer:
y= 35
Step-by-step explanation:
y directly proportional to x
where x= 2, y= 10
y=kx
10= k× 2
k= 10/2
k= 5
to find y when x is 7
y = kx
y = 5× 7
y= 35

some soiled goods are sold for 2 /5 of their original price. what will be the selling price of a pair of trouser originally Costing#850.00
Answer:
The selling price of the goods is #340.00
Step-by-step explanation:
Given;
original price, P = #850.00
the new cost = 2/ 5 of the original price
The selling price of the goods is calculated as follows;
[tex]= \frac{2}{5} \ \times \#850\\\\ = \# 340[/tex]
Therefore, the selling price of the goods is #340.00

Find the value of x. please show step by step process.
Answer:
x=44
Step-by-step explanation:
alright to make this easy we have to find out all of the angles values. If you see those little lines, then they are indicating that the opposite angles are similar. so angles b and d are equal to 34. in order for a triangle to be true all of the angles added up have to equal 180 so to find the last angle we do 180 -34 -34 which equals 112. That is the angle of c on the bottom triangle. The angle next to is is suplementary meaning that those two angles added together will equal 180. If one angle is 112 we just subtract 112 from 180 to get the other angle which is 68. Once again we have the two little lines indicating that the two angles are the same. Again we do 180 - 68 - 68 which is 44. Therefore x =44
