Answer:

1/√3

Step-by-step explanation:

(1/√2)(1/√2)(2/√3)

1/√3

Answer 2

Answer:

1

Step-by-step explanation:

Values : -

Sin 45 = 1 / √2

Cos 45 = 1 / √2

Cosec 30 = 2

Sin 45 • Cos 45 • Cosec 30

= Sin 45 × Cos 45 × Cosec 30

= ( 1 / √2 ) × ( 1 / √2 ) × 2

= ( 1 / 2 ) × 2

= 2 / 2

= 1

Therefore,

Sin 45 • Cos 45 • Cosec 30 = 1
