Answer 1

Answer:

probably the correct answer will be..option A

Answer 2

Answer:

Ans 1 : 7/4

Step-by-step explanation:

Cos0° = 1

Sin30° = 1/2

Sin45° = 1/√2

Sin90° = 1

Cos60° = 1/2

Cos45° = 1/√2

(Cos0° + Sin30° + Sin45°)(Sin90° + Cos60° - Cos45°)

= (1 + 1/2 + 1/√2)(1 + 1/2 - 1/√2)

= [(1 + 1/2) + 1/√2] [(1 + 1/2) - 1/√2]

(a + b)(a - b) = a² - b²

= (1 + 1/2)² - (1/√2)²

= 1 + 1 + 1/4 - 1/2

= (4 + 4 + 1 - 2)/4

= 7/4
