If cos Θ = negative 4 over 7, what are the values of sin Θ and tan Θ? sin Θ = ±square root 33 over 7; tan Θ = ±square root 33 over 4 sin Θ = ±3 over 7; tan Θ = ±square root 33 sin Θ = ±33 over 7; tan Θ = ±square root 33 over 7 sin Θ = ±square root 33 over 7; tan Θ = ±square root 33 over 7

Answer = Option A;

sinθ = ±

tanθ = ±

Step-by-step explanation:

cosθ =

Remove the negative sign and evaluate cosθ = 4/7

cosθ = adjacent/hypotenuse.

Please see attached image for the right-angle triangle representation.

Let opp = length of opposite side of the triangle.

Let adj = length of adjacent side of the triangle.

Let hyp = length of hypotenuse side of the triangle

Using Pythagoras theorem,

Take the square root of both sides.

±

opp = ±

sinθ = opposite/hypotenuse

sinθ = ±

tanθ = opposite/adjacent

tanθ = ±

0 is its x and y coordinate
