Question

hi answer for you by the above question.​

Answer 1

Answer:

5/2

Step-by-step explanation:

[Sec²54 - Cot²36 / Cosec²57 - Tan²33] + 2Sin²38*Sec²52 - Sin²45

Cot36 = Cot(90 - 54) = tan54°

Tan33 = Tan(90-57) = cot57°

Sin38 = Sin(90-52) = Cos52°

//substitute the above values back

[Sec²54 - Tan²54 / Cosec²57 - Cot²57] + 2Cos²52*Sec²52 - Sin²45

=> [1 / 1] + 2*1 - (1/√2)²

=> 1 + 2 - 1/2

=> 5/2
