I am assuming you mean 4/7 as the sine or cosine cannot be higher than 1.
Lets find <span>θ,
</span>
θ = [sin-1](4/7) = 34.85 °
But lets take into account that this value is the equivalent in Quadrant I.
If Θ lies in Quadrant II , then θ = 180 ° - 34.85 ° = 145.15 °
So cosθ = cos (145.15) = -0.821

Answer:
D 21
Step-by-step explanation: x/7 = 3
isolate x by multiplyig both sides by 7: (7)(x/7) = (3)(7)
x = 21
