Answer 1

I can't see the triangle image. Please either upload the image or tell me the two side lengths (the side adjacent to θ and the hypotenuse). Then I can compute

θ = arccos(adjacent / hypotenuse)

and pick the correct answer.

Quick note: the choices correspond roughly to these ratios:
- 59.5° → cos θ ≈ 0.51
- 43° → cos θ ≈ 0.73
- 30.5° → cos θ ≈ 0.86

So if you tell me the adjacent and hypotenuse (or their ratio) I’ll give the exact choice.
