Answer:
91/17
Step-by-step explanation:
Cotθ = 15/8.
Tanθ = 8/15.
Cosecθ = √1 + Cot²θ = √1 + (15/8)² = 17/8.
Sinθ = 8/17
Secθ = √1 + Tan²θ = √1 + (8/15)² = 17/15
Cosθ = 15/17.
4Cotθ - 5Secθ - 8Cosecθ/5Tanθ + 4/3Cotθ - 17Sinθ
= 4*15/8 - 5*17/15 - 8*17/8 / 5*8/15 + 4/3*15/8 - 17*8/17
= 15/2 - 17/3 - 17 / 8/3 + 5/2 - 8
= 45 - 34 - 102/6 / 16 + 15 - 48/6
= -91/6 / -17/6 = 91/17.
