What is the sine and cosine of 240
2 answers:
Sin(240) = -√(3)/2
sin(240) = 2sin(120)cos(120)
sin(240) = 2[2sin(60)cos(60)cos(120)]
sin(240) = 2[2[2sin(30)cos(30)cos(60)cos(120)]]
sin(240) = 2[2[2[2sin(15)cos(15)cos(30)cos(60)cos(120)]]]
sin(240) = 16sin(15)cos(15)cos(30)cos(60)cos(120)
cos(240) = ⁻¹/₂
cos(240) = cos¹⁶(15) - sin¹⁶(15)

Answer:
5
Step-by-step explanation:
5*10^5=500000 and 1*10^5=100000
Cost of items = $23.45
Tax = 8% of $23.45 = 0.08*23.45 = $1.88
Tip = 20% of $23.45 = 0.2*23.45 = $4.69
Total cost = 23.45 + 1.88 + 4.69 = 30.02
Answer: $30.02
