Answer:
2.1
Step-by-step explanation:
using cosine theorem or substraction of two vector
b = AC = 5
c = AB = 6
a² = b² + c² - 2bc cos A
a² = 5² + 6² - 2*5*6 cos 20°
a² = 4.62
a = √4.62
a = 2.149
a ≈ 2.1
3.1 kg
4.3+5.3+ 6.8+ 2.6 + 3.2 +4.4 +4.8= 31.4 kg
Last fish= y
(31.4 + y)÷ 8= 4.3125
31.4 + y= 4.3125 x 8
y= 34.5 - 31.4
∴ y= 3.1 kg
#3 is 40 degrees Clockwise.
The answer is 15 - p = k
