Question

If 15 cot A = 8, find the other five trigonometric
ratios of ZA.
A​

Answer 1

Answer:

$\cot( a) = \frac{8}{15} = \frac{b}{p}$

$h = \sqrt{ {p}^{2} + {b}^{2} } = \sqrt{64 + 225} = \sqrt{289} = 17$

$i.e \: \: \sin(a) = \frac{15}{17}$

$\cos(a) = \frac{8}{17} \: \tan(a) = \frac{15}{8}$

Answer 2

Answer:

Cot A =8/15

Tan A =15/8

SecA = (tan2A+1)^1/2 =17/8

Cos A = 8/17

Sin A = 15/17

Cosec A= 17/15
