Question

(cosOº + sin30° + sin 45°( sin 90° + cos 60° - cos 45%) = ?​

Answer 1

Answer:

1

Step-by-step explanation:

cos0+sin30+sin45(sin90+cos60-cos45%)

1+1/2+1/root 2(1+1/2-1/root 2

solve  this

Answer 2

Answer:

1+1/2+1/√2(1+1/2-1/√2)

3/2+1/√2(2/2-1/√2)

[3+√2]/2(3-√2)/2

now solve this

and get the answer
