The reference angle is an acute angle that angle in standard position makes with the positive x-axis.
The given angle in radians is
This angle is already acute and hence it is itself a reference angle.
The reference angle of any angle in the first quadrant is the same angle.
A decade is 10 years which means 1/5 is 2 years. thus making 2/5 4 years.
Answer:
14 hours
Step-by-step explanation:
Let's call the task 3x
The older bro does twice as younger so it would be 2x long and younger brother work x long
Since the totsl of work is 3x = 21 x woul be 21÷3 = 7
the older brother must work 2 × 7 = 14 hours long
If at least one has to be heads then it would be 1/5
4 + 3 + 1 = 8
450000 divided by 8 = 56250
The first person gets 225000.
The second person gets 168750.
The last person gets 56250.
