Question

Given 15 tan A = 8, Find cos A and cosec A.​

Answer 1

Answer: cosA= 15/17 and  cosecA = 17/8

Step-by-step explanation:

15tanA = 8

tanA = 8/15

since tan A= perpendicular/base,

hypotenuse = $\sqrt{8^2 + 15^2 }$ (from pythagoras theorem)

hypotenuse = 17

Now, cosA = base/hypotenuse = 15/17

similarly, cosecA = hypotenuse/perpendicular = 17/8
