The Answer would be )C 4/5 = 0.8
Because 4/5 As a Decimal is 0.8 and 0.8 is equal to 0.8 Nor Greater or Less.

Question: Assume the complete question as, Two forces of 20 Newton’s and 30 Newton’s² act on a point. The resultant force is 40 Newton’s. Find the angle between the two forces
Answer:
75.5°
Step-by-step explanation:
From the question,
Using cosine rule,
R² = P²+Q²-2PQcosθ................... Equation 1
Where θ angle between the the two forces.
Given; R = 40 Newton, P = 20 Newton, Q = 30 Newton.
Substitute these values into 1
40² = 20²+30²-[2×20×30(cosθ)]
1600 = 400+900-(1200cosθ)
1600 = 1300-1200cosθ
1200cosθ = 1600-1300
1200cosθ = 300
cosθ = 300/1200
cosθ = 0.25
θ = cos⁻¹(0.25)
θ = 75.5°
Hence the angle between the forces is 75.5°

Answer:
a) 4w + 16 = 50.
Step-by-step explanation:
The garden's length is obviously 8 feet longer than the width. If width were represented by w, the length would be w + 8.
We are calculating the perimeter, which is 2 times the length plus 2 times the width. That adds up to be 50.
2(w) + 2(w + 8) = 50
2w + 2w + 16 = 50
4w + 16 = 50
So, the answer is a) 4w + 16 = 50.
