my brother did that too but I'm sorry i cant help you but I'm gonna say just keep up the good work
Ratio of 30-60-90 triangles in terms of side lengths is 1-
![\sqrt{3} ](https://tex.z-dn.net/?f=%20%5Csqrt%7B3%7D%20%0A)
-2
So, the side across the 30-degree angle is 6.25.
Thus, the side across the 90-degree angle (hypotenuse) is 12.5.
Circumference of circle having radius 2 meters is 12.56 meters
Step-by-step explanation:
Radius of circle = 2 m
Circumference of circle = ?
The formula used to find Circumference of circle (C) is:
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
Putting values and finding circumference
![C=2\pi r\\C=2*3.14*2\\C=4*3.14\\C=12.56\,\,meters](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r%5C%5CC%3D2%2A3.14%2A2%5C%5CC%3D4%2A3.14%5C%5CC%3D12.56%5C%2C%5C%2Cmeters)
So, Circumference of circle having radius 2 meters is 12.56 meters

Answer:
Rate of depreciation per year is 4310 $/ year and the depreciation schedule is given below.
Step-by-step explanation:
According to the question,
since, it is straight-line depreciation,
rate of depreciation per year =
$/year
= 4310 $/ year
So we can prepare the following table. (year = 0 for the base period)
Year Depreciation Accumulated Book value
