Question : If $\sin \alpha=\frac12$ and $\sin \beta=\frac12$, then what is the value of $\cos (\alpha+\beta)$? $(0°<\alpha, \beta<90° )$
Option 1: $\frac{\sqrt{3}}{2}$
Option 2: $\frac{1}{ 4}$
Option 3: $\frac12$
Option 4: $1$
Correct Answer: $\frac12$
Solution : Given, $\sin \alpha=\frac12$ and $\sin \beta=\frac12$ and $0°<\alpha, \beta<90°$ $\sin \alpha=\frac12=\sin30°$ ⇒ $\alpha =30°$ $\sin \beta=\frac12=\sin30°$ ⇒ $\beta=30°$ So, $\cos(\alpha+\beta)=\cos(30°+30°)=\cos60°=\frac{1}{2}$ Hence, the correct answer is $\frac12$.
Question : P and Q are two alloys of Aluminium and Copper. The ratios of Aluminium and Copper in P and Q are 5 : 11 and 3 : 5, respectively.
