Answer:
tan 5π/24.
Step-by-step explanation:
We use the identity:
tan (A - B) = (tan A - tan B) / (1 + tan A tan B)
so the first expression simplifies to
tan ( π/3 - π/8)
= tan 5π/24.
To convert a decimal into a percentage, first we have to convert it into fractional form.
Because percentages are out of 100, the resulting fraction would be 3/100.
Next, to find the decimal, we would just divide the fraction (numerator divided by denominator).
3 % = 3/100 = 0.03

Answer:
Step-by-step explanation:
Let the gross salary be x.
<u>Then after deduction it becomes:</u>
- x - 22% =
- x(1 - 0.22) =
- 0.78x
<u>Since the amount is known, the gross salary is:</u>
- 078x = 2880
- x = 2880/0.78
- x = 3692 rounded to whole number
<u>Answer</u>: $3692
