Answer 2

il this one ill put it in better wat

Answer 3

way

Answer 4

Draw a right triangle and label one of the acute angles θ. arctan(4) tells us the side opposite θ has length 4, and the side adjacent to θ has length 1 (TOA). So the hypotenuse of this triangle is
√(16 + 1) = √17

Then then sin(θ) = 4/√17 (SOH)
