The ratios in a 30-60-90 triangle are 1 :
: 2. Therefore, since the hypotenuse is the longest and it is 10, 10 / 2 is 5 meaning 5 is the smallest side.
P = 8 + 10 + 8 + 10
P = 36
..................................
Answer:
C.
Step-by-step explanation:

This can be solve by using the formula
D = P( 1 – i)^n
Where d is the depreciation value after n years
P is the initial value
i is the depreciation rate
n is the years
D = 1/3 ( 1800)
D = 600
So
600 = 1800 ( 1- 0.45)^n
Solve for n
