Multiplying we have:

We round the expression and we have that it is equivalent to: 20.
Thus,
is approximately equal to 20.
Answer:
The expression given is approximately equal to 20.
Option C
This angle will be smaller than 108*. So when we know it will be multiplied by 2 C and D are automaticly marked off.
A or B. 36 times 2 = 72 72 times 2 = 144.
If we look at the angles they are less than 90* so our answer would be A. 36*.
