Answer:
n = 10
Step-by-step explanation:
The triangles are equal by SSS theorem, therefore the 2 angles given with a variable must be equal.
Regular pentagon means the shape with 5 sides which their lengths are equal to each other.
so, if the total perimeter of the pentagon is 10s - 20,
we can find the length of each side by dividing it by 5.
(10s - 20) / 5
we can expand this equation by dividing each number in the bracket by 5
= 2s - 4
Therefore, the answer should be D.
1/6x >= 5
6 (1/6x)>=6 (5)
x>=30
35,32,40
The Law of Conservation states that energy can neither be created or destroyed. So I believe the answer should be A, since the Light energy is being converted and not destroyed and then made again
hope this helps
