E Correct answer
Explanation

sin 30 = 0.5 and cos 60 = 0.5. Adding these gives 0.5 + 0.5 = 1. Option E is correct.

AI explanation

sin 30° = 0.5 and cos 60° = 0.5, because sine and cosine of complementary angles (30° and 60° add to 90°) are equal — sin(30°) = cos(90°-30°) = cos(60°). Adding them gives 0.5 + 0.5 = 1.
