To simplify the expression, we need to first find the values of cos(50°) and cos(130°).
cos(50°) ≈ 0.6428cos(130°) ≈ -0.6428
Now, substitute these values back into the expression:
3 + 3cos(50°) / (1 - cos(130°))= 3 + 30.6428 / (1 - (-0.6428))= 3 + 1.9284 / 1.6428= 3 + 1.1747= 4.1747
Therefore, 3 + 3cos(50°) / (1 - cos(130°)) simplifies to approximately 4.1747.

cos(130°) ≈ -0.6428
Now, substitute these values back into the expression:
3 + 3cos(50°) / (1 - cos(130°))
= 3 + 30.6428 / (1 - (-0.6428))
= 3 + 1.9284 / 1.6428
= 3 + 1.1747
= 4.1747
Therefore, 3 + 3cos(50°) / (1 - cos(130°)) simplifies to approximately 4.1747.
