Answer 2

Answer:

3 / 160

Step-by-step explanation:

cos Ө = 3 / 5

sin Ө = 4 / 5

cot Ө = 3 / 4

tan Ө = 4 / 3

(Ratios can be found by drawing a right angled triangle and using Pythagoras thm $a^{2}$ + $b^{2}$ = $h^{2}$)

(sin Ө - cot Ө) / 2 tan Ө

= (4 / 5 - 3 / 4) / 2 (4 / 3)

= ((16 - 15) / 20) / (8 / 3)

= 1 / 20 * 3 / 8

= 3 / 160
