Percent means parts out of 100
20%=20/100=2/10=1/5
a mixed number is a fraction over 1 expressed in the form (whole number) and (fraction part)
since this is less than one, it techinally is not a mixed number but we can do this
0 and 1/5
There is one cake
It is divided among x family members, so each gets:
1/x
The father took 1/5 which is 4 times greater than each one's piece. So:
1/5 = 4(1/x)
1/5 = 4/x
x = 20
There are 20 family members so the answer is none of these

Answer: 19.1</h3>
====================================================
Work Shown:
tan(angle) = opposite/adjacent
tan(C) = AB/BC
tan(theta) = x/BC
tan(23) = (8.1)/BC
BC*tan(23) = 8.1
BC = (8.1)/tan(23)
BC = 19.0824041631723
BC = 19.1
In this case, rounding to 3 sig figs means we round to the nearest tenth.
Make sure your calculator is in degree mode.
Answer: 27 degrees
Step-by-step explanation:
