Question

If 15 tan Φ = 8 Find the value of cos Φ and cosec Φ ​

Answer 1

Answer:

15 tan ¢ =8

tan¢ =8/15

Perpendicular=8 units

Base=15 units

hypotenuse=?

let hypotenuse be X,base be Y and perpendicular be Z

X²=Y²+Z²

X²=15²+8²

X²=225+64

X²=289

X=√289

X=17units

Cos¢=base/hypotenuse

=15/17

Cosec¢=hypotenuse/perpendicular

=17/8
