Answer:
cosjk = √55 i/3
tanjk = 8/√55 i
Step-by-step explanation:
Given
sin jk = 8/3
According to SOH CAH TOA
Sin theta = opposite/hypotenuse = 8/3
Opposite = 8
hypotenuse = 3
Get the adjacent using the pythagoras theorem
hyp² = opp²+adj²
adj² = hyp² - opp²
adj² = 3² - 8²
adj² = 9-64
adj² = -55
adj = √-55
adj = √55 i (i = √-1)
Get cosjk
cosjk = adj/hyp
cosjk = √55 i/3
Get tanjk
tanjk = opp/adj
tanjk = 8/√55 i

Answer: 
45 grams
Step-by-step explanation:
1st order: 27 people
15 people:
100 g
Ginger: 20 g
Turmeric: 25 g
Coriander: 35 g
Cumin Seeds: 20 g
20+25+35+20=60+40=100
For 1 person:
Ginger: 1 1/3 g
Turmeric: 1 2/3 g
Coriander: 2 1/3 g
Cumin Seeds: 1 1/3 g
Multiply all that by 27
For 27 people: 
Ginger: 36 g
Turmeric: 45 g
Coriander: 63 g
Cumin Seeds: 36 g
45 g for Turmeric
