Question 1166535: From an observatory tower A,a column of smoke is sighted due south from a second tower B,5km west of A,the smoke is observed in the direction S60°E,how far is the fire from B?also how far is the fire from A? Answer by solver91311(24713) (Show Source):
Since B to the Fire is 60 degrees East of South, angle B of the triangle must be 30 degrees, so you have a 30-60-90 triangle. The ratio of the three sides hypotenuse:short leg:long leg is
But you want the ratio where the long leg has the value 1 and then you can multiply each of the ratio values by 5 to find the other two legs. To get this ratio, multiply each of the values in by
