Answer:
1350
units²
Step-by-step explanation:
The regular hexagon consists of 6 equiangular triangles
The area (A) of a equilateral triangle is calculated as
A =
( s is the side length )
Here s = 30 , then
A =
=
= 225
units²
Thus the area of the regular hexagon is
area = 6 × 225![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
= 1350
units² ← exact value
≈ 2338.3 units² ( to 1 dec. place )

Answer: C) x = 80</h3>
==================================================
Work Shown:
Let's cross multiply to get the following
14/20 = 56/x
14*x = 20*56
14x = 1120
x = 1120/14
x = 80
-------------------
As a way to check the answer, we can type 14/20 - 56/80 into the calculator and we should get 0. I'm taking advantage of the rule that if A = B, then A-B = 0. This trick is handy to check if two sides of any equation are equal to one another.
Answer:
Step-by-step explanation:
Hello, please consider the following.
m and n are the two numbers.
m + n = 24, right?
n = 2 m
We replace n in the first equation, it comes
m + 2m =24
3m = 24 = 3*8
So, m = 8 and n = 16
Thank you

Answer:
Angle D and Angle B
<em> </em><u><em>OR</em></u>
Angle A and Angle C
Step-by-step explanation:
These 2 angles are vertical angles (meaning they are congruent to one another) because they are directly opposite from each other.
