If θ is an acute angle and 24 sinθ + 7 cosθ = 25 , find the value of \(\frac{sinθ}{tanθ}\) + cosθ. |
\(\frac{25}{14}\) \(\frac{14}{25}\) 0 1 |
\(\frac{14}{25}\) |
In equation → 24 sinθ + 7 cosθ = 25 If the coefficients of sinθ and cosθ and constant are making a triplet then → 24 sinθ + 7 cosθ = 25 ↓ ↓ ↓ P B H Therefore, \(\frac{sinθ}{tanθ}\) + cosθ = \(\frac{sinθ}{\frac{sinθ}{cosθ}}\) + cosθ = cosθ + cosθ = 2 cosθ = 2 × \(\frac{7}{25}\) = \(\frac{14}{25}\) |
