To solve this, we simply divide the total amount of land by the amount of mosh in one bag:
350/2 = 175
You need 175 bags of mosh
718,956;716,480;715,230;714,398;713,486;712,396;710,469;709,612;708,421;706,329
First we have to find the missing angle. And we know that sum of the measurement of angles of a triangle is 180.
So we will get

Now we use sine law, which is

Substituting the values, we will get


The formula of area of triangle, for the given triangle is


Angles that equal 180 degrees
