Question

Given that sin α = ½ and cos β = ½, then the value of α + β is ______

​

Answer 1

Answer : 90° ✔️ Solution : Given that : sinA = 1 / 2 and cosB = 1 / 2 On solving : sinA = 1 / 2 = > sinA = sin30° = > A = 30° And cosB = 1 / 2 = > cosB = cos60° = > B = 60° Now , A + B = > 30° + 60° = 90° I hope it will be helpful for you ☺️ Fóllòw MË ❤️
