If tan A = $\frac{3}{7}$, then what is the value of cosec A ? |
$\frac{2\sqrt{10}}{3}$ $\frac{7\sqrt{10}}{20}$ $\frac{\sqrt{58}}{3}$ $\frac{3}{\sqrt{58}}$ |
$\frac{\sqrt{58}}{3}$ |
tanA = \(\frac{3}{7}\) { given } By using pythagoras theorem , P² + B² = H² 3² + 7² = H² H² = 49 + 9 H² = 58 H = \(\sqrt { 58}\) Now we find, cosecA = \(\frac{H}{P}\) = \(\frac{√58}{3}\) |
