If cos x = $\frac{24}{25}, 0 ≤ x ≤ 90°,$ then the value of cot x + cosec x is : |
0 1 7 $\frac{7}{2}$ |
7 |
cosx = \(\frac{24}{25}\) { cosx = \(\frac{B }{H}\) } P² + B² = H² P² + 24² = 25² P = 7 Now, cot x + cosec x = \(\frac{B }{P}\) + \(\frac{H }{P}\) = \(\frac{24 }{7}\) + \(\frac{25 }{7}\) = \(\frac{49}{7}\) = 7 |
