912.501 is your answer. :)
Sin60 = X/10√ ̅3
X=15 cm
And in triangle: (10√ ̅3)^2 = 15^2 + y^2
Y=√ ̅75= 5√ ̅3
The answer is D

Answer:
It will take the apprentice 24 days working alone
Step-by-step explanation:
Let the number of days it takes the apprentice be x
It will take the landscaper x/3 ( since he is three times faster)
The rate for both will be 60/6 = 10 sq m per day
Rate for apprentice is 60/x
rate for the boss is 60/x/3 = 180/x
Adding the rates together;
60/x + 180/x = 10
240/x = 10
240 = 10x
x = 240/10
x = 24 days
