Question

1.2 tan^245° + cosec^2 30° – sin^2 60°+2 sec^245°
​

Answer 1

Step-by-step explanation:

37/4

2×1+4-3/4+4

=2+4-3/4+4

=10-3/4

=37/4 ans

Answer 2

Answer:

8.45

Step-by-step explanation:

Tan 45 = 1

Cosec 30 = 2

Sin 60 = √3/ 2

Sec 45 = √2

1.2 (1) + 2^2 - ( √3/2)^2 + 2 ( √2)^2

1.2 + 4 - 0. 75 + 4

8.45
