If $sin A =\frac{1}{2}$, then the value of $(tan A + cos A)$ is: |
$\frac{3}{3\sqrt{3}}$ $\frac{3}{2\sqrt{3}}$ $\frac{5}{2\sqrt{3}}$ $\frac{5}{3\sqrt{3}}$ |
$\frac{5}{2\sqrt{3}}$ |
We are given that :- sinA = \(\frac{1}{2}\) { we know, sinA = \(\frac{P}{H}\) } By using pythagoras theorem, P² + B² = H² 1² + B² = 2² B² = 4 - 1 B = \(\sqrt {3 }\) Now, tanA + cosA = \(\frac{P}{B}\) + \(\frac{B}{H}\) = \(\frac{1}{ √3 }\) + \(\frac{√3}{2}\) = \(\frac{5}{ 2√3 }\) |
