#4 should be the third choice.
#1 is -0.36 .
4. It can be helpful to consider the identities related to each of the answer choices.
• cot(θ) = 1/tan(θ) . . . . 1/tan(θ) + tan(θ) ≢ 1
• sec(θ) = 1/cos(θ), csc(θ)=1/sin(θ) . . . . 1/cos(θ)² + 1/sin(θ)² =
(sin(θ)²+cos(θ)²)/(sin(θ)²cos(θ)²) = 1/(sin(θ)²cos(θ)²) ≢ 1
• sec(θ) = 1/cos(θ), tan(θ) = sin(θ)/cos(θ) . . . . (sin(θ)/cos(θ))² ≡ sin(θ)²×1/cos(θ)²
tan(θ)² = sin(θ)²×sec(θ)² is the correct choice
• sec(θ) = 1/cos(θ), tan(θ) = sin(θ)/cos(θ) . . . . cos(θ)² ≠ 1/cos(θ)²×(sin(θ)/cos(θ))²
1. cot(290°) = -tan(20°) ≈ -0.36
The second selection is a better choice.

"Inversely" generally means the relationship is proportional to the reciprocal.
y = k/x
42 because he won 35 so 5 times 7 equals 35 so you would multiply the other side by seven and 6 times 7 is 42
No it is not because its more then ten numbers away from the solution of the five tickets
