Question

plzz answer with explanation ​

Answer 1

Answer:1/2

Step-by-step explanation:

sinθ = 4

          5

sinθ= opposite

       hypotenuse

opposite² + adjacent² = hypotenuse²

4²+ adjacent² = 5²

adjacent side = 3

tanθ = opp./adj. = 4/3

cosθ= adj./hyp. = 3/5

secθ = hyp./adj = 5/3

cotθ = adj/opp = 3/4

( now substituting values )

4×4/3 - 5×3/5 =   16/3  -  3  =     (16-9)/3    =     7/3     =     7×3  =   1

5/3 + 4×3/4          5/3+3             (5+9)/3          14/3            3×14      2
