Answer 2

Answer:

451/60

Step-by-step explanation:

Let this symbol ● be theta ..for convenience ..likhne me aasani hogi

cos ● = 3/5 = base/hypotenus or b/h

we know, h² = p² + b²

So, p² = h² - b²

p² = 25 - 9 = 16

therefore, p = 4

Now lets find the values of other trigonometric ratios

tan● = p/b = 4/3

cot● = b/p = 3/4

sec● = h/b = 5/3

cosec● = h/p = 5/4

We have been given the following expression to solve

2 tan● - cot●/3sec● +4cosec●

2×(4/3) - (3/4) / 3×(5/3) + 4×(5/4)

8/3 - 3/20 + 5

(160 - 9 + 300) / 60

451/60

I hope I didn't make any mistake ...
