Answer 2

Answer:

$\text{Given: 15 Cot A = 8} \\\\\implies \text{ Cot A } = \dfrac{ 8}{15} \\\\\implies \text{Cot A} = \dfrac{Cos A }{Sin A} \\\\\implies \dfrac{8}{15} = \dfrac{Cos A}{Sin A }$

Now we know that, two sides are 8 and 15. Hence let us find the hypotenuse of the triangle.

Applying Pythagoras Theorem:

=> 8² + 15² = Hypotenuse²

=> 64 + 225 = Hypotenuse²

=> 289 = Hypotenuse²

=> Hypotenuse = √289 = 17

Hence the sides of the triangle are: 8, 15, 17.

$Sin A = \dfrac{ 8}{!7} \\\\Sec A = \dfrac{1}{CosA} = \dfrac{ 1}{ \dfrac{15}{17} } = \dfrac{17}{15}$

Hence these are the required values.
