Answer:
Yes you would know
Step-by-step explanation:
We can view these tents as sides on a shape that is 30 sided, with lines connecting each tents together.
After this we calculate the interior angle of each side, and use our given 20m to calculate it.
You can use the fact that equivalent equations are such that one equation can be obtained by performing some operations(which doesn't break equality) on the other equation and vice versa.
The equivalent equation to
is 
<h3>What are equivalent equations?</h3>
Equivalent equations are such that one equation can be obtained by performing some operations(which doesn't break equality) on the other equation and vice versa.
<h3>How to get the equivalent equation of the given equation?</h3>
The given equation is

Subtracting 4 from both sides, we get

Thus, one equivalent equation to the given equation is

Heya!
Here is your answer:
2 ×

+10
we know that,

= 9
so,
2×9 +10
According to BODMAS (bar, Order, division, multiplication, addition, subtraction)
we multiply 2×9 = 18
then,
18+ 10
= 28
