Answer:

No solution

Explanation:

sin^2θ + cos^2θ = 1

Substituting sinθ = 34:

(34)^2 + cos^2θ = 1

Simplifying:

cos^2θ = 1 - (34)^2

cos^2θ = 1 - 1156

cos^2θ = -1155

Since cosθ is negative in Quadrant II and the cosine of an angle cannot be negative, there is no real-valued solution for cosθ in this case.
